Unit pricing base measure [unit_pricing_base_measure]

A custom icon for Merchant Center Classic and Merchant Center Next.

The unit pricing base measure [unit_pricing_base_measure] attribute lets you show how the price of your product translates per the indicated unit. For example, if you were selling a 150-millilitre bottle of perfume, you could show customers how much your perfume costs per 100 millilitres.

Minimum requirements

These are the requirements that you'll need to meet to show your product. If you don't follow these requirements, we'll disapprove your product and let you know in your Merchant Center account.

  • Submit the unit pricing measure attribute to define the measure and dimension of your product. For example, if you submit GBP 3 as the value for the price [price] attribute, 150 fl oz as the value for the unit pricing measure [unit_pricing_measure] attribute and 100 fl oz as the value for the unit pricing base measure [unit_pricing_base_measure] attribute, the unit price would be GBP 2 for every 100 fl oz.

Best practices

These best practices can help you to go beyond the basic requirements to optimise your product data for performance.

  • Use the same type of units for this attribute as you use for unit pricing measure. For example, if you use sqm for the unit pricing measure, then also use sqm for the unit pricing base measure

Additional guidelines

Review each section closely to determine whether the requirements apply to your country or product. If you don't follow requirements that apply to you, we'll disapprove your product and let you know in your Merchant Center account. 

United Kingdom only
  • Submit metric values when targeting the UK. The imperial units (for example, fl oz, pt, qt, gal) are interpreted as US imperial units, which are different than the imperial units used in the UK.
