Every machine file and field operation includes a units map (GET /files/{id}/units or GET /operations/{id}/units) that maps each numeric property to its unit string.
The units you receive are controlled by the unitMeasurement configuration, which accepts three values: DEFAULT, IMPERIAL, or METRIC. Set it at the API owner or Leaf user level in Configuration.
Always check the units endpoint for the specific file or operation rather than assuming units from the tables below. Rate and product-specific units can vary by operation content.
The same unit strings appear in both summary stat objects ({ "avg": 4.93, "min": 2.43, "max": 6.39, "unit": "mi/hr" }) and in the standalone units map ("speed": "mi/hr").
Default
These are the units when unitMeasurement is set to DEFAULT.

Default — Harvested
Default — Tillage
Imperial
These are the units when unitMeasurement is set to IMPERIAL.
