Question

How much is 168 cm in feet and inches?

Answer 1

Hint: There are 12 inches in a foot and 1 foot equals 30.48 cm, which can be taken to be 30.5 for small lengths, the difference between the two values being of the order of 2 cm for lengths close to 6 feet.
Since the feet and inches do not follow a multiple of 10 relation, it would be better to calculate the values separately for them instead of simply dividing 168 by 30.48.
1 inch is equal to 2.54 cm.

Complete step-by-step answer:
3.48 cm equals 1 foot. Therefore, 30.48 × 5 cm equals 1 × 5 feet.
⇒ 152.4 cm = 5 feet.
Now the remaining length, 168 − 152.4 = 15.6 cm, can be converted into inches by dividing by 2.54.
 $\dfrac{15.6}{2.54}$ = 6.14
Therefore, 168 cm = 152.4 cm + 15.6 cm = 5 feet and 6.14 inches.

Note: The French revolution (1789 - 99) provided an opportunity for the French to reform their unwieldy and archaic system of many local weights and measures.
The units of the metric system, originally taken from observable features of nature, are now defined by seven physical constants being given exact numerical values in terms of the units. In the modern form of the International System of Units (SI), the seven base units are: meter (m) for length, kilogram (kg) for mass, second (s) for time, ampere (A) for electric current, kelvin (K) for temperature, candela (cd) for luminous intensity and mole for amount of substance.
