The following buttons can be used to quickly change all relevant settings between Metric and Imperial units and vice versa.

  • Metric

Formatting

Distance

Type

Choose from the drop-down list:

  • Centimetres
  • Feet
  • Inches
  • Metres
  • Millimetres
  • Points

Suffix

Enter the required distance unit suffix, such as mm, cm etc.

Decimal places

Enter the required number of decimal places to be displayed for distances.

Increment

This is the value by which distances will be incremented or decremented when using the spin-box controls on entry fields.

Display fractions

Switch this option on if you want to display fractions rather than decimal values.

Denominator

Enter the denominator to be used for fractions.

Reduce denominator

Switch this option on if you want fractions displayed with the lowest possible denominator. For instance, display 5/10 as 1/2.

Weight

Type

Choose from the drop-down list:

  • Grams
  • Kilograms
  • Ounces
  • Pounds

Suffix

Enter the required weight unit suffix, such as gm, kg etc.

Decimal places

Enter the required number of decimal places to be displayed for weights.

Increment

This is the value by which weights will be incremented or decremented when using the spin-box controls on entry fields.

Display fractions

Switch this option on if you want to display fractions rather than decimal values.

Denominator

Enter the denominator to be used for fractions.

Reduce denominator

Switch this option on if you want fractions displayed with the lowest possible denominator. For instance, display 5/10 as 1/2.

Angle

Type

Choose from the drop-down list:

  • Degrees
  • Gradients
  • Radians

Suffix

Enter the required angle unit suffix, such as deg, rad etc.

Decimal places

Enter the required number of decimal places to be displayed for angles.

Increment

This is the value by which angles will be incremented or decremented when using the spin-box controls on entry fields.

Display fractions

Switch this option on if you want to display fractions rather than decimal values.

Denominator

Enter the denominator to be used for fractions.

Reduce denominator

Switch this option on if you want fractions displayed with the lowest possible denominator. For instance, display 5/10 as 1/2.

Volume

Suffix

Enter the required volume unit suffix, such as cu mm.

Area

Suffix

Enter the required area unit suffix, such as sq mm.

Round up area display

Switch this option on to round large area values up to display them in a bigger unit, such as metres.

Threshold

Enter the value above which area values should be displayed in the bigger unit.

Number

Decimal places

Enter the required number of decimal places to be displayed for real numbers (i.e. not distance, weight or angle).

Standards

When running standards it is possible to automatically apply rounding to a specified threshold. For example you may wish to round all values to 0.5mm or 1/16inch.

Apply threshold rounding

Switch this option on to use this facility.

Default rounding threshold

Enter the required value.

Floating point arithmetic rounding errors may cause some standards to give unexpected results if they have not been designed with this in mind. Using a global arbitrary epsilon value in rounding expressions may compensate for this.
