Feet and Inches Calculations
The feet should be entered as whole numbers and inches can be entered as either fractions or mixed numbers or a combination of both. The answer will be returned as a mix of fraction and a whole number, if a fraction exists in the answer.
- Enter feet as whole numbers only.
- Enter inches as mixed numbers i.e. as whole numbers or fractions in the following formats:
- Mixed numbers may be written as 1 1/2 which is one and one half or 35 4/35 which is thirty five and four thirty-fifths.
- Keep exactly one space between the whole number and the fraction, e.g.
Fractions as 2 3/4 which is two and three fourths or 8 3/100 which is eight and three one hundredredths.
