The Canadian Grain Commission has released a new online tool to help producers quickly and accurately determine the volume and test weight of their grain.

“As a producer, I understand how important it is to have accurate data about my crop. These calculators are an easy way to get accurate conversion results and give farmers another tool to use in managing their operation.”

Doug Chorney

• Test weight, or bushel weight, is a measure of a grain’s density, which is expressed as the weight of the grain packed in a specified volume.

• Test weight is a grade-determining factor for many grains under the Canada Grain Act.

• The Canadian Grain Commission’s conversion charts and calculators were developed by collecting data from a wide range of grain samples and determining their half-litre weights and their corresponding compacted hectolitre weights.

• A grain’s test weight is commonly expressed as kilograms per hectolitre (kg/hL) or pounds per bushel (lb/bu).

• The size of a bushel is not the same in Canada and the United States. In Canada, the bushel is based on the Avery (Imperial) bushel (36.37 L), which is slightly larger than the Winchester (U.S.) bushel (35.24 L).

Canadian Grain Commission

The Canadian Grain Commission is the federal agency responsible for establishing and maintaining Canada’s grain quality standards. Its programs result in shipments of grain that consistently meet contract specifications for quality, safety and quantity. The Canadian Grain Commission regulates the grain industry to protect producers’ rights and ensure the integrity of grain transactions.
