Farm At Hand has an extensive list of units of measurement that you can choose for each record.
You can change the unit of measurement used for a record by clicking into the record details and then selecting a unit from the drop-down list:
Here are some things to keep in mind when selecting a unit:
changing the unit for a record will not automatically convert the volume
when transferring to a contract, the unit will be locked to the same unit as the contract
a contract's unit depends on the commodity, but we are working on unlocking it to allow you to change the unit to what you need it to be.
