Enter feet and inches using the following format:
feet'-inches" or feet' inches" or feet'inches"
You can separate feet, inches, and fractional inches with a dash, a space, or nothing. You can use any of the following syntax cases to enter valid feet-inch formatted values:
- 5' or 60”
- 5'-9” or 5' 9” or 5'9”
- 5'-1/2” or 5' 1/2” or 5'1/2”
- 5'-9-1/2” or 5' 9-1/2” or 5'9-1/2”
- 5'-9 1/2” or 5' 9 1/2” or 5'9 1/2”
To designate inches for linear calculations, entering double quotes (“) is optional. For example, instead of entering 5'9-1/2”, you could enter 5'9-1/2.
Danger: With imperial units, CAL interprets a minus or a dash (-) as a unit separator rather than a subtraction operation. To specify subtraction, include at least one space before or after the minus sign. For example, to subtract 9” from 5', enter
5' -9” rather than
5'-9”.
