In mathematics, the metric system, Feet, and Meters are both a form of distance measurement. Both forms help in calculating the length of an object or subject. Meter is one of the fundamental length units according to the International System of Units. It is equal to 3.2 feet or 3 feet 2 inches. Feet refers to many units of measurement.
Feet are denoted by ft.
Meter is denoted by a small m.
Know what one meter equals in feet- One meter equals 3.28 feet. For a precise measurement, 1 meter is equal to 3.28084 feet. This can be rounded off to 3.28 feet. 3.28 feet is normally used as it’s easy to do sums with simple and easy numbers.
2) Multiplying the number by 3.28 - When we are provided with a measurement in the form of meters, and we need to convert it into feet, the measurement in meters must be multiplied by 3.28.
For example- 5 meters is to be converted into feet. To know the measurement in feet, we need to multiply 5 by 3.28 and hence, we get the answer 16.4 feet.
\begin{array}{l}
5 \times \3.28 \\
=16.40
\end{array}
3) Converting the answer into inches - The next step while converting meters to feet involves converting the answer into inches. Sometimes, the answer is too long; we need to convert it into inches to make the answer short and simple. To do so, we must take the decimal point and everything after it and multiply it by 12.
For example, 5 meters we need to convert into feet; we multiply 5 by 3.28 and get the answer 16.4. Later on, to simplify it, we take 0.4 and multiply it by 12 we get the answer 4.8. Hence the answer we finally get is 16 feet and 4.8 inches.
It is really simple.
It is easy to understand.
Feet differ in length from country to country.
It needs to be more consistent.
Feet are as long as one person’s foot.
Does not provide an accurate result.
If one meter makes 3.28 feet, one foot makes approximately 0.3048 meters.
1 foot=0.3048 meter.
Foot refers to measuring only one single unit, whereas feet are the measurement of two or more units. Feet are the plural form.
Meter gives more accurate results than feet.
To get the answer in feet and inches, the point decimal and everything after that must be multiplied by 12.
\begin{array}{l}
15 \times \3.28 \\
= 49.20
\end{array}
=49.20 ft
\begin{array}{l}
0.2 \times \12 \\
= 2.4
\end{array}
= 2.4 inches
Therefore the final answer is 49 feet and 2.4 inches.
No, the calculation of feet or the measurement that we get in feet is only sometimes accurate.
