Many liquid products are sold by volume rather than by individual units. Whether you’re selling chemicals, paints, cleaning products, oils or liquid fertilisers, customers often need to buy an exact number of litres.
WooCommerce doesn’t include litre-based pricing by default, but it can be configured to automatically calculate prices based on customer-entered quantities.
In this guide, we’ll show you how to sell products by litre in WooCommerce.
Why Sell Products by Litre?
Selling by litre allows customers to purchase exactly the amount they need.
Common examples include:
- Agricultural chemicals
- Cleaning products
- Paint
- Resin
- Engine oil
- Lubricants
- Liquid fertiliser
- Pond treatments
- Adhesives
- Food-grade liquids
Instead of creating dozens of fixed-size products, customers simply enter the quantity they require.
Example Pricing
Suppose you sell industrial cleaner for:
£3.50 per litreA customer enters:
25 litresWooCommerce calculates:
25 × £3.50 = £87.50The price updates instantly before the customer adds the product to their cart.
Why Fixed Product Variations Become Difficult
Some stores attempt to create variations such as:
- 1L
- 5L
- 10L
- 20L
- 25L
- 50L
This quickly becomes difficult to manage, especially when customers require custom quantities.
Dynamic pricing removes the need to maintain dozens of product variations while offering far more flexibility.
Automatically Calculate Prices
A measurement pricing solution allows customers to:
- Enter the number of litres required

These can all be included within the pricing formula.
