Metric remains the source
All product dimensions and capacities are maintained in millimetres, millilitres and litres. These values remain authoritative.
Calculated reference units
The site calculates inches, US fluid ounces and US gallons for international comparison. Values are rounded to two decimal places.
Names stay metric
A 20 L container remains a 20 L container. It is not renamed as a five-gallon model unless the original mould is explicitly designed to that standard.
