Choose a meter stick or metric tape measure. Select a metre stick ruler or tape measure with meter (m) or centimeter (cm) printed on it. These tools will make it easier to calculate square meters since they were designed in the same measurement system.
Measure the length of the area you’re measuring. Square meters are a unit for measuring the 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 metre, remember to include both the meter and centimeter parts of the measurement. For instance, “2 meter 35 centimeters.”
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 centimeter). 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 get round to the nearest centimeter 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 millimeter measurements.
Convert from centimeters to meters. Usually, the measurements won’t divide evenly into metres. Instead, you’ll have a measurement in both meter and centimeter, for example, “2 meters 35 centimeters.” Because 1 centimeter = 0.01 meters, you can convert a centimeters 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 meter, multiply them together to get the measurement of the area in square meter. Use a calculator if necessary. For example:
2.35m x 1.08m = 2.538 square metres (m2).
Round to a more convenient measurement. If you get a long decimal as an answer, for instance, 2.538 square meter, 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 metre, the last digits probably aren’t accurate anyway. In most cases, you can round to the nearest centimeter (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 three to determine how many rolls of grass you’ll need. Please ensure that when you order grass from Grass Factory & Eco Organics, you communicate the square meters or the number of rolls you require.
IMPORTANT: Remember that grass/instant lawn is a natural product supplied in rolls. The grass rolls are not rigid or solid and are subject to break and have a slight deviation in size due to their nature. It is very important to add 10% over and above the actual area size, to have adequate material for coverage.
