Units

Figures knows about a wide array of units, and you can use them most places you would use numbers.

25km + 400m
80 - 20m
collect(2..5 meters)
25m / 5m
25.4 km
60 m
[2 m, 3 m, 4 m, 5 m]
5

NOTE

The collect function gathers all the elements of a range into a list

Prefixes

All SI units like meters and grams can be used with metric prefixes. Figures combines unit names with prefix terms as in kilometers and milligrams. Unit symbols are combined with prefix symbols like in km and mg.

Data units like bits and bytes are inherently binary values and therefore use a different scale.

Conversions

To convert between different units, use one of the conversion operators as, to, in, or format.

Figures has a deep understanding of units and can do calculations and conversions between different unit types.

25kg × 30m² / 5s² in joules
42m/s² × 2sec in mph
150m × 30m in acres
150 J
187.9 mph
1.11 ac

NOTE

Currency units are unique because their relative values change over time. By default, Figures updates currencies once per day. To configure currency updates, go to Preferences > Units

Regional Units

Some units have different meanings in different regions. There are areas that use U.S. Customary system for units like cups and tons. Others use the Imperial system for those units.

NOTE

Figures attempts to set the correct system for your region. If you want to change this setting, go to Preferences > Format > Region

No matter which system is set, you can always specify which unit you want by prefacing regional units with US or UK. These examples assume regional preference is set to U.S. Customary.

2 cups in uk cups
2 us cups in uk cups
3 uk pints as us gallons
us tons to uk tons
1.67 UK cup
1.67 UK cup
0.45 gal
0.89 UK ton

Customizing Units

In addition to the hundreds of units supported by Figures, you can also add your own custom units or tweak existing ones. Got to Preferences > Units to view all the units that are available, sorted by category. Use the filter bar to quickly find a unit.

Editing Units

Double-click on a unit to edit it.

Unit preferences

Each of the name fields has a toggle that can make the name case sensitive. See Variables for more detail on case sensitivity.

When Figures displays a unit in the results panel, it prefers using the symbol if there is one. Otherwise it uses the primary name or an alternate name. There is an example after the Format field that shows how the unit will be displayed.

Creating Units

Click the + button at the top of the unit list to create a new unit.

Unit preferences

The fields are the same as those for existing units with a couple exceptions. First, the Kind field is editable. By selecting a kind, your custom unit will be convertible to other units of the same kind. Second, custom units have a value in terms of another unit. The units available in the Value field are determined by the selection of Kind.

Once created, your custom unit can be used exactly like built-in units.
