Information on test weight

Test weight is the measure of grain density determined by weighing a known volume of grain. In Canada's grain grading specifications, it is expressed in grams per 0.5 litre or kilograms per hectolitre. Test weight is a grading factor for many grains under the Canada Grain Act.

The following information describes how grain is measured for test weight, provides current minimum test weights for Canadian grain grades, and includes test weight conversion charts and answers questions about test weight and how grain volumes are measured.
