Inputs

First value — feet Enter whole feet; negatives allowed for subtractions like −3 ft.

First value — inches Use mixed numbers (7 1/2), fractions (5/8), or decimals (7.25).

Operation Choose add, subtract, multiply, or divide.

Second value — feet For × or ÷ you can leave feet empty and enter a pure number in inches.

Second value — inches Mixed (4 5/8), fraction (5/8), or decimal (4.625). For × or ÷ this can be a plain number.

Enter feet as whole numbers, inches as mixed numbers (e.g., 9 1/8), simple fractions (e.g., 5/16), or decimals (e.g., 9.125).

Internally, values convert to total inches, the operation is applied, then results convert back to feet and fractional inches in lowest terms.

For multiply or divide, treat the second value as a scale: leave its feet blank and enter a plain number in the inches box.
