Square meters are a measurement of area, usually used to measure a 2-dimensional infinite such as a field or floor.^[1] For example, you might measure the footprint of a burrow in foursquare meters, then measure your living room in square meters to come across if it will fit. If you just have a ruler or measuring record that uses feet or another non-metric unit of measurement, you can nonetheless use it to calculate the area, then catechumen to square meters.

one
Choose a meter stick or metric tape measure. Select a meter stick ruler or record measure with meters (m) or centimeters (cm) printed on it. These tools will brand it easier to calculate square meters, since they were designed in the same system of measurement.
- If you can only find a ruler with feet (ft) or inches (in), measure with those instead, then go to the section on converting to square meters.
two
Measure the length of the expanse you're measuring. Square meters are a unit for measuring area, or the size of a ii-dimensional object such equally a floor or a field. Use your measuring tool to measure one side of the object, from one corner to the other.^[2] Write down the result.
- If the object is longer than i meter, remember to include both the meter and centimeter parts of the measurement. For case, "2 meters 35 centimeters."
- If you want to measure an object that isn't rectangular or square, read the Complex Shapes section instead.

If yous can't measure the unabridged length at in one case, do information technology in stages. Lay out the measuring tool, then put down a rock or other pocket-sized object exactly at an easy to remember mark (like 1 meter or 25 centimeters). Option up the tool and lay it down once again, starting at the pocket-size object. Repeat until the entire length is covered, and add all your measurements together.
- If the room isn't rectangular, break it into a number of small rectangles, then measure those. For case, if the room is L-shaped, break that upwards into 2 non-overlapping rectangles.^[three]
4
Measure out the width. Use the aforementioned tool to measure the width of the same area or object. The side you measure in this footstep should be angled shut to 90º abroad from the length of the object you measured before, like two sides of a square next to each other.^[4] Write this number down also.
- Unless the object yous're measuring is much smaller than 1 meter, you can round to the nearest centimeter when making your measurements. For case, if the width is slightly past the 1 meter viii centimeter mark, just utilise '"1m 8cm" as your measurement, without using decimals or millimeter measurements.
5
Convert from centimeters to meters. Usually, the measurements won't divide evenly into meters. Instead, you'll accept a measurement in both meters and centimeters, for example "2 meters 35 centimeters." Because 1 centimeter = 0.01 meters, y'all can convert a centimeter measurement into meters by moving the decimal point two digits to the left. Here are a couple examples:^[v]
- 35cm = 0.35m, so 2m 35cm = 2m + 0.35m = 2.35m
- 8cm = 0.08m, then 1m 8cm = 1.08m
6
Multiply the length and width together. Once both measurements are converted into meters, multiply them together to become the measurement of the area in square meters.^[six] Use a calculator if necessary. For example:
- 2.35m 10 1.08m = 2.538 square meters (m²).
7
Circular to a more convenient measurement. If you get a long decimal as an respond, for example 2.538 square meters, you'll probably want to round it to a number with fewer digits, for instance two.54 square meters. In fact, since you probably didn't mensurate correctly down to the tiniest fraction of a meter, the final digits probably aren't accurate anyway. In nearly cases, you lot can round to the nearest centimeter (0.01m). For a more accurate measurement, larn how to circular to the meaning digits.
- Whenever you lot multiply two numbers with the same units (for instance, meters), the answer is always in the form of that unit squared (yard², or square meters).

1
Multiply square feet by 0.093. Mensurate the length and width in anxiety and multiply them together to get a result in foursquare feet. Since 1 square pes = 0.093 square meters, multiply your result by 0.093 to get the respond in foursquare meters instead.^[7] Square meters are bigger than square feet, so information technology will take fewer of them to cover the same expanse.
- For greater precision, multiply by 0.092903 instead.
2
Multiply foursquare yards by 0.84. If you have the measurement in square yards, multiply by 0.84 to get the measurement in square meters.^[8]
- For greater precision, multiply by 0.83613 instead.
iii

Multiply acres by 4050. Ane acre contains nigh 4050 square meters. If yous want to be more precise, multiply by 4046.ix instead.^[9]
iv
Convert foursquare miles to square kilometers instead. One foursquare mile is much, much larger than a foursquare meter, and so typically information technology is converted into square kilometers instead. Multiply the square miles by 2.6 to detect the area in square kilometers instead. (Or multiply by 2.59 instead to be more precise.)^[10]
- If you really want to catechumen to square meters, 1 square kilometer = ane,000,000 foursquare meters.
v
Convert square meters to units of area, non length. Square meters are a unit that measures area, or 2-dimensional surfaces. It doesn't make any sense to compare them with units that measure length, or altitude in i direction. You tin convert between "square meters" and "square anxiety," but not between "foursquare meters" and "feet."
- Don't use the calculations in this section to convert between units of length. That requires unlike numbers.

Break the shape up into pieces. If yous are solving a math problem, describe or cutting lines in the shape to divide information technology into simpler shapes, such equally rectangles and triangles. If you are measuring a room or other physical object, sketch a diagram of the expanse first, then do the same thing. Take measurements of each section and write them on the diagram.^[eleven] Follow the instructions below to discover the expanse of each section, then add the results together.
two
Measure out rectangle shaped pieces as you would ordinarily. To find the area in foursquare meters for rectangular sections, see the instructions for calculating an surface area in square meters.
- If you are measuring in a dissimilar unit, look at the section on other units.
3
Measure out right triangles similarly, then separate by 2. A right triangle, which has a 90º bending just like the corners of a square, has an area easy to calculate. Measure the two sides next to that 90º corner (the length and width), multiply them together, then dissever by two to become the reply in square meters.^[12]
- This works because a right triangle is exactly the size of a rectangle cut in one-half. Basically, yous institute the area of a rectangle as usual, and then divided by 2 to go the area of the triangle.
4

Turn other triangles into correct triangles, then measure them. Describe a line from whatever corner of a triangle to the opposite side, and so that the line hits the reverse side at a 90º angle (picture the corner of a foursquare). You've just divided the triangle into two pieces, each one a right triangle! See in a higher place for instructions on how to find the expanse of a correct triangle; measure each of the 2 sub-triangles separately, and add them together.
v
Calculate the area of a circumvolve. The surface area of a circle is πr^two, where r is the radius, or altitude from the center of the circumvolve to the rim, or perimeter.^[13] Measure this distance, multiply it by itself, then multiply the effect by π on a reckoner. If you lot don't have a calculator with a π role, utilize 3.14 instead (or three.1416 if high precision is required).
- If you're non sure where the center is, accept a friend hold a tape measure and walk around the border of the circumvolve. Agree the other end of the tape mensurate and adjust your position until the measurement stays the same while your friend walks around the entire edge.
- More complicated curved boundaries require more than advanced math to calculate. If you are measuring a room for practical purposes, it might exist easier to estimate the area by pretending the curved surfaces are a series of straight lines.

You can't really convert directly from square meters to cubic meters. Square meters are a measure of expanse (which is 2 dimensional), while cubic meters are a measure out of volume (3 dimensional). To calculate the volume of a space in cubic meters, measure the length, width, and tiptop in meters and multiply them together.

If the room is rectangular, measure the length and width of the room in meters, then multiply those dimensions together. If the room is not a perfect rectangle (e.thousand., if information technology has an apse), you'll need to split up the room into rectangular (or triangular) portions. Find the expanse of the principal part of the room and add it to the area of the alcove or extension.

Article Summary X

To calculate square meters, beginning measure out the length of the area you're measuring. Then, measure out the width. Convert any centimeters in your measurement to meters. For example, if the length you measured is 2 meters and 35 centimeters, you would convert the 35 centimeters to meters by moving the decimal point ii digits to the left, which would requite y'all 0.35 meters. Therefore, the length is 2.35 meters. Finally, multiply the length and width to get the number of foursquare meters. For example, if the length is two.35 meters and the width is 2 meters, you lot would multiply 2.35 by ii and get four.seven. Therefore, the surface area yous're measuring is 4.7 square meters. If you're measuring in feet instead of meters, kickoff catechumen any inches in your measurements to anxiety past dividing the number of inches by 12. For example, if the width of the expanse you're measuring is x anxiety and 5 inches, y'all would carve up 5 by 12 and get 0.42. Therefore, the width is ten.42 feet. Multiply the length by the width to become the number of foursquare feet, then multiply the number of square anxiety by 0.093 to find the number of square meters. For instance, if the area you're measuring is two square feet, you would multiply 2 past 0.093 and become 0.186. Therefore, the area is 0.186 square meters.
