Choose a meter stick or metric tape measure. Select a meter stick ruler or tape measure with meters (m) or centimetres (cm) printed on it. These tools will make it easier to calculate square meters since they were designed in the same system of measurement.
Measure the length of the area you’re measuring. Square meters are a unit for measuring area or the size of a two-dimensional object such as a floor or a field. Use your measuring tool to measure one side of the object, from one corner to the other. Write down the result.
If the object is longer than 1 meter, remember to include both the meter and centimetre parts of the measurement. For instance, “2 meters 35 centimetres.”
If you can’t measure the entire length at once, do it in stages. Lay out the measuring tool, then put down a rock or other small object precisely at an easy to remember mark (like 1 meter or 25 centimetres). Pick up the tool and lay it down again, starting at the small object. Repeat until the entire length is covered, and add all your measurements together.
Measure the width. Use the same tool to measure the width of the same area or object. The side you measure in this step should be angled close to 90° away from the length of the object you measured earlier, like two sides of a square next to each other. Write this number down as well.
Unless the object you’re measuring is much smaller than 1 meter, you can round to the nearest centimetre when making your measurements. For instance, if the width is slightly past the 1 meter 8-centimeter mark, just use “1m 8cm” as your measurement, without using decimals or millimetre measurements.
Convert from centimetres to meters. Usually, the measurements won’t divide evenly into meters. Instead, you’ll have a measurement in both meters and centimetres, for example, “2 meters 35 centimetres.” Because 1 centimetre = 0.01 meters, you can convert a centimetre measurement into meters by moving the decimal point two digits to the left.
Here are a couple examples:
35cm = 0.35m, so 2m 35cm = 2m + 0.35m = 2.35m
8cm = 0.08m, so 1m 8cm = 1.08m
Multiply the length and width together. Once both measurements are converted into meters, multiply them together to get the measurement of the area in square meters. Use a calculator if necessary. For example:
2.35m x 1.08m = 2.538 square meters (m2).
Round to a more convenient measurement. If you get a long decimal as an answer, for instance, 2.538 square meters, you’ll probably want to round it to a number with fewer digits, for example, 2.54 square meters. In fact, since you possibly didn’t measure correctly down to the tiniest fraction of a meter, the last digits probably aren’t accurate anyway. In most cases, you can round to the nearest centimetre (0.01m).
Whenever you multiply two numbers with the same units (for instance, meters), the answer is always in the form of that unit squared (m2, or square meters).
You can take the square meter figure and multiply it by 3 to determine how many rolls of grass you’ll need. Please ensure when you order grass from Grass Factory & Eco Organics that you communicate the square meter or the number of rolls you require.
