Centimeter also spelt as a centimetre, is a unit of length equivalent to 0.01 meter in the metric system. The SI symbol used to represent centimeters is cm. The centimeter is defined as the base unit of length in the old centimeter - gram - second (CGS) system of units.

Although for most of the physical quantities, SI prefixes for factors of 10³- like milli and kilo are mostly preferred by the technicians, the centimetre remains the standard unit of length for many daily life measurements. The centimeter is widely used to measure things that are too big for millimeters but too small for meters. A centimetre is close to the width of the fingernail of an average adult person.

The centimeter-scale can be widely understood with the help of a ruler. A standard ruler measures up to 30 cm, as one shown below. When looking at the ruler, you will find cm along the top and inches (1 inch = 2.54 cm) along the bottom.

The centimeter is frequently used to measure the small distance between objects or dimensions of small objects in real-life situations.

A centimeter chart can be constructed to represent the conversion of units from centimeters to other units of measurements such as meters, inches, feet, etc. Using the centimeter chart, we can easily learn the conversion of units from centimeters to other units of measurement. Let us now discuss, how to convert cm to inches, centimeters to feet, and centimeters to meters.

As we know, 1 inch is equivalent to 2.54 cm in the metric system.

1 inch = 2.54 cm

Or

1 cm = 1/2.54 inches

Hence, to convert cm to inches, we will divide the centimeters value by 2.54.

We can also convert centimeters to inches by multiplying the centimeters value by 0.3937 because one centimeter is approximately equal to 0.3937 inches.

For Example:

To convert 10 cm to inches, we will either divide 10 cm by 2.54 or multiply 10 cm by 0.3937 to get the value in inches i.e 10 / 2.54 = 3.93700 inches or 10 0.3937 = 3.937 inches.

Hence, 10 cm = 3.9370 inches.

To convert a centimeter measurement to a meters measurement, we will divide the centimeter value by 100 because 1 centimeter is equal to 1/ 100 meters.

For Example:

To convert 500 centimeters into meters, we will divide 500 cm by 100 i.e. 500/100 = 5m

Hence, 500 cm = 5 m.

To convert a centimeter measurement to a feet measurement, we will multiply the centimeter value by 0.0328084 because 1 cm is approximately equal to 0.0328084 feet.

For Example:

To convert 5 centimetres into feets, we will multiply 5 cm by 0.0328084 i.e. 5 0.0328084 = 0.164042 feet.

Hence, 5 cm = 0.164042 feet.

The word “centimeter” is derived from the French centimeter, a combination of the Latin word centum, which means hundred, and the French word meter.

The word centimeter was introduced in the year 1801 and has been widely used since then.

The value of one imperial foot is equivalent to 30.5 cm approximately.

The value of a United States Nickel (5 cm) coin is approximately 2 cm in diameter.

1. What is the value of 30 cm in inches?

Solution:

As we know, 1 cm = 0.3937 inches

To get the value of 30 cm in inches, we will multiply 30 cm by 0.3937.

= 30 × 0.3937

= 11.811 inches

Hence, 30 cm is equal to 11.811 inches

2. How to convert 43 cm into feet?

Solution:

As we know, 1 cm = 0.0328084 ft

To convert 43 cm into feet, we will multiply 43 cm by 0.0328084 feet.

= 43 × 0.0328084

= 1.4107612 inches

Hence, 43 cm is equal to 1.4107612 inches.

3. What is the value of 50 cm in meters?

Solution:

As we know, 1 cm = 1/100 m

To get the value of 100 cm in meters, we will divide 50 cm by 100.

= 50/100

= 0.5 meters

Hence, 50 cm is equal to 0.5 meters.
