Unit Conversion

Note: This feature is available only for certain plans of Zoho Inventory. Visit the pricing page to check if it’s available in your current plan.

Unit Conversion in Zoho Inventory automatically lets you convert an item’s base unit to another unit while creating transactions. Once you configure a default unit for sales and purchase transactions, Zoho Inventory will automatically convert the base unit of an item to the default unit that you’ve configured.

Let’s look at a scenario where this feature will be useful.

Scenario: John, who owns a hardware shop, buys electrical wiring from his supplier in meters and sells them to his customers in centimeters. Instead of manually calculating and converting the wires from meters to centimeters in sales transactions, John sets up unit conversions and sets centimeters as the default unit of measurement for sales transactions. Now, whenever he creates a new sales transaction for electrical wiring, Zoho Inventory automatically converts the unit of electrical wires to centimeters based on the conversion rate that he’s configured.

Unit Conversion is now enabled for your organization, and you can proceed to set it up.

Set Up Unit Conversion

To set up Unit Conversion, you need to first configure Unit Precision for the base unit and the target unit. The precision of a unit is the number of digits you want after the decimal point. You can increase the unit precision based on how precise you want the conversion to be.

To configure Unit Precision:

Warning: Once you set the unit precision for a unit, you won’t be able to reduce it.

If you’ve configured multiple conversions for the same unit, you can choose any of them while creating transactions.
