Entering values in imperial unit system formats

Values can be entered in the imperial unit system, as well as in the metric unit system.

Note: If millimeters need to be entered in the imperial unit system, the mm suffix must added to the value.

Feet, inches and fractions of an inch can be separated from each other by a dash, a space, an underscore, or nothing:

feet'-inches" or feet' inches", feet'_inches", or feet'inches"

Example:

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"

5'-9 1/2" or 5' 9 1/2" or 5'9 1/2"

-5' -9 -1/2" of 5'--9--1/2" of 5'_-9_-1/2"

The quotation mark " is always optional. Instead of 5'-1/2" it is possible to use 5'-1/2.

To specify a subtraction, it is mandatory to put at least one space or underscore before or after the minus sign. By subtracting, for example 5 feet minus 9 inch, enter 5' -9 " or 5'_-9". Entering 5'-9" will not be considered a subtraction.

When the arithmetical functions * (multiply) and / (divide) are included in the entered value, the following rules apply:

• Multiply and divide operators have precedence on the add and subtract operators.

• In the imperial unit system, the divide operator needs to be preceded by a blank or an underscore.

• If the feet and inch indicators are omitted, the part in front of the multiply or divide operator is considered to be in inches, and the part after the operator is considered to be a factor value.
