INCH-FOOT DEFINITION
An in-ft is a measure of how much material is to be cut.
An in-ft is defined as: depth in inches times length in feet.
Example: How many in-ft are in this doorway?
1. Determine the depth of the cut in inches.
For this example, 8 inches.
2. Determine the length of the cut in feet.
3+7+3+7=20 feet
3. Multiply the two numbers
8 in x 20 ft = 160 in-ft
1sq-m = 129 in-ft
