## Built-In Mathematical Operations

The software is able to perform a number of calculations whenever a numerical value is entered.

### Automatic Unit Conversion

If you enter a value using a different unit of measurement than the default unit, the software will automatically convert the value to the default unit.

For example, if your default unit is inches, you can enter a value of 1 ft, and the software will convert the measurement to 12 in.

Supported units are:

 in, " inch ft, ' foot mm millimeter cm centimeter m meter pt point

### Simple Mathematical Operators

If you enter a simple mathematical expression, the software will calculate the result of the expression and enter that value in the field.

The available mathematical operators, in order of precedence, are:

 / Division * Multiplication + Addition - Subtraction

For example, if you enter 1/8, the value 0.125 will be calculated.

Operator precedence determines the order in which mathematical operations will be calculated when more than one operation is specified. In the table above, operators are listed from top to bottom in order of their operator precedence. For example, if you enter 6/2*3, the software will calculate 6/2 first, then multiply the result by 3, yielding a result of 9.

### Calculation of Ratios

If you enter a ratio in the format A:B, the software will scale the previous value in the field by the ratio entered.

For example, if a value is set to 12, and you enter 2:3, the new value will be 8.

### Calculation of Percentages

If you enter a percentage in the format X%, the software will scale the previous value in the field by the percentage entered.

For example, if a value is set to 10, and you enter 90%, the new value will be 9.
