Answer: 168 cm becomes 5 feet and 6 inches after conversion,
There are 12 inches in a foot, and 1 foot is equal to 30.48 cm. For smaller lengths, we often round this value to 30.5 cm, which introduces only a minor difference of about 2 cm for measurements close to 6 feet. Since feet and inches don’t follow a simple multiple of 10 relation, it’s better to convert them separately instead of dividing 168 cm directly by 30.48.
1 inch = 2.54 cm.
Step-by-Step process:
1. Convert centimeters to feet:
168 cm ÷ 30.48 cm/foot ≈ 5.51 feet.
This gives 5 feet as the whole number.
Step-by-Step process:
1. Convert centimeters to feet:
168 cm ÷ 30.48 cm/foot ≈ 5.51 feet.
This gives 5 feet as the whole number.
2. Convert remaining centimeters to inches:
The leftover length is: 168 cm- 152.4 cm = 15.6 cm.
To convert 15.6 cm into inches: 15.6cm÷2.54cm/inch≈6.14 inches.
Thus, 168 cm is approximately 5 feet 6 inches.
Historical Context
During the French Revolution (1789–1799), France saw a chance to simplify and unify the way things were measured. Before that, different regions used all kinds of confusing and inconsistent systems. To fix this, they introduced the metric system, a new way of measuring things, based on natural elements like the distance around the Earth.
Today, the metric system, now called the International System of Units (or SI), is based on seven fixed scientific values, known as physical constants. These constants help define the exact meaning of each unit we use. The main units include the meter for length, kilogram for weight, second for time, ampere for electric current, kelvin for temperature, candela for brightness, and mole for measuring amounts of substances. This system helps keep measurements consistent and accurate all over the world.
