Centimetres To Feet and Inches
1 centimetre = 0.0328084 foot 1 foot = 30.48 centimetres 1 centimetre = 0.393701 inch 1 inch = 2.54 centimetresTo convert centimetres to feet and inches first you have to convert the centimetres into decimal feet format.
Converting 325 cm into decimal feet
325 * 0.0328084 = 10.66273 decimal feetThe value before the digit becomes the foot value. Foot = 10 subtract the foot value from the decimal feet value and the result is the decimal inch value that is left after removing the foot value.
10.66273 - 10 = 0.66273multiply this decimal inch value by 12 to remove the whole inches ( 1 foot = 12 inches)
0.66273 * 12 = 7.95276The value before the digit becomes the inch value. Inch = 7.
subtract the inch value from the decimal inch value
7.95276 - 7 = 0.95276 0.95276 is the fraction of an inch in decimal format.Convert the decimal to a fraction and simplify if possible.
Multiply the decimal value by a 1 plus the required amount of "0's" to remove the digit it will always be one zero more than there are numbers behind the digit. The amount your are multiplying with will be the denominator, the result of the multiplication, the numerator
0.95276 * 100000 and the fraction becomes 95276/1000000 which can be simplified to 23819/250000Add the foot and inch to this and you end up with 10' 7 23819/250000"
If you need to use this amount for an measurement then this is not a very useful result. To create a usable fraction you first have to multiply the decimal fraction amount by an amount that you would like to have as the denominator of the fraction. Keep in mind that a larger denominator can produce a more accurate result. This is not always true but depends on the decimal amount.
If you need the denominator to be 16th of an inch then multiply the decimal by 16 to get the numerator result
0.95276 * 16 = 15.24416 round this amount to a whole number. Since it is closer to 15 than 16 the numerator of the fraction becomes a 15.
The fraction here = 15/16
Result of converting 325cm to feet and inches using 16 as the denominator = 10' 7 15/16"
Denominator at 64th of an inch, multiply the decimal by 64 to get the numerator result
0.95276 * 64 = 60.97664 round this amount to a whole number. Since it is closer to 61 than 60 the numerator of the fraction becomes a 60.
As you can see here the amount that is rounded is much smaller than in the 16th example and thus it is more accurate.
The fraction here = 61/64
Result of converting 325cm to feet and inches using 64 as the denominator = 10' 7 61/64"
Using 2 as the denominator:
0.95276 * 2 = 1.90552 round this amount to a whole number. Since it is closer to 2 than 1 the numerator of the fraction becomes a 2.
The fraction here = 2/2
In this case 2/2 = 1 and there would be no fraction. The1 is added to the inch value.
Result of converting 325cm to feet and inches using 2 as the denominator = 10' 8"
