How to convert from feet and inches to cetimeters?

To find how many centimeters are in 5 feet and 11 inches, you should firstly know that:

  • 1 foot = 0.305 meter = 30.5 centimeters (this means that to convert from feet to cm, you just need to multiply the value in feet by 30.5).

  • 1 inch = 2.54 centimeters (this means that to convert from inches to cm, you just need to multiply the value in inches by 2.54).

So,

5 feet = 5 x 30.5 cm = 152.5 cm

11 inches = 11 x 2.54 cm = 27.94 cm

Now, once both values are already expressed in the same unit (cm), we can sum them once 5 feet and 11 inches is the same as 5 feet plus 11 inches. so,

5 feet + 11 inches = 152.5 cm + 27.94 cm = 180.44 cm

A faster way to convert from feet and inches

There is a formula to speed up this process.

cm = 30.5 x ft + 2.54 x in

Taking the values of the example above, we have

Value in cm = 30.5 x 5 + 2.54 x 11 = 152.5 + 27.94 = 180.44 cm.

The formula above "says" that

"To covert from feet and inches to cm, you just need to multiply the feet value by 30.5, multiply the inches value by 2.54 and finally, sum the two results to get the value in centimeters".
