# Units of Measure¶

You may use the unit names or abbreviations, and most names can be either singular, hour, or plural, hours. Please see the math.js documentation for details.

Note

set_metric units use standard SI unit names from the math.js library, with the exceptions noted below. You can combine them for compound units like rates and ratios. Other units may not scale appropriately in charts. Please contact us if you require help with an unusual or custom unit.

Observe recommends using full names for clarity. Note that both names and abbreviations are case-sensitive. The metric does not contain a unit if you omit unit:. You may also use unit:"" to indicate values without units.

Units based on the B scale by a factor of 1000 on inboard cards. the metric value displays with larger units as its value increases. For example, 1,000 B bytes is 1 kB.

To scale by 1024, use By units: By, KiB, MiB, GiB, or TiB.
