Here, we will not only show you what 642 centimeters is in feet and inches, but also show you
how we converted 642 cm to feet and inches.
First things first. 642 cm in feet and inches is:
21 feet and 31/41 inches
Here is the math, with an explanation to show you how we converted 642 centimeters into
feet and inches:
There are 0.393701 inches in a centimeter, so to convert 642 cm to inches only, we did this:
+ 0.393701 x 642
= 252.756042 inches
There are 12 inches in a foot. To get the number of feet, we divided inches by 12. The number to
the left of the decimal is the number of feet:
+ 252.756042 / 12
= 21.0630035 feet
= 21 feet
Then, we subtracted the feet from the answer above and multiplied the result by 12 to get inches. The number to the left
of the decimal is the number of inches.
+ 21.0630035 - 21
= 0.0630035
+ 0.0630035 x 12
= 0.7560420
= 0 inches
Finally, we made the leftover (remainder) from above into a fraction with a 2 digit accuracy as follows:
+ 0.7560420 - 0
= 0.7560420
0.7560420 converted to fraction
= 31/41 fraction of an inch
And once again, you have your answer:
642 cm = 21 ft 31/41 in
