# Product Unit Conversions

Use Product Unit Conversions to tell Consignly how many of the stocked unit make up another unit.

You can chain your units together, to configure different pack sizes for the product.

*Unit conversions defined in Consignly*

After defining the unit conversion(s), tell Consignly which ones to use when working out metrics on a consignment, or when calculating storage for the warehouse.

*Checkboxes indicating which metric conversions are enabled for consignment metrics and storage metrics.*

## Working out consignment metrics

Check the boxes to determine which conversions will be used to calculate consignment metrics. The Metric Resolution method will determine how these are broken down.

If you check none of the boxes then the stocked unit is the only unit involved in the consignment metric calculation.

## Working out storage metrics

Check the boxes to determine which conversions will be used to calculate storage metrics. The Metric Resolution method will determine how these are broken down.

If you check none of the boxes then the stocked unit is the only unit involved in the storage metric calculation.

## Metric Resolution

The dropdown under the Consignment and Storage columns allows you to choose how metrics will be used in each of these cases.

*Metric Resolution set to Cascade for consignment metrics, and Compound for storage metrics.*

Consider a product with the following unit conversions:

**Stocked Unit**: Cartons**Conversion**: 6 cartons to a tray**Conversion**: 6 trays to an outer**Conversion**: 16 outers to a pallet

Suppose you create an outwards consignment of 584 cartons.

If you choose to cascade the consignment metrics, then this will break the metrics down from largest unit to smallest unit, so the metrics on the consignment will look like this:

- 1 pallet
- 1 tray
- 2 cartons

If you choose to compound the metrics, then this will work out a unit metric at each unit type that has been turned on in the product.

Following on from the example above, consignment metrics would look like this:

- 1.014 pallets
- 16.222 outers
- 97.333 trays
- 584 cartons

## What are the metrics used for?

Consignment metrics are used to calculate charges raised on activity, freight and other things within a consignment.

Storage metrics are used to calculate charges for storage in a warehouse.
