The metric system of weights and measures, while dominant in most countries, has not been universally embraced.

Many states still use a mixture of legacy and metric measures. The UK, for instance, still commonly uses acres for land area, but metric for weight, giving the mongrel yield measure of tonnes per acre.

The US has largely stuck by its legacy measures, such as the bushel. And, as an extra complication, its bushel weights vary between crops.

And this before getting on to the idiosyncrasies of some soft commodity markets, with coffee selling in bags, and cotton in bales.

The calculators allow readers to switch easily between the major measures.
Area - Acres, hectares and bigger measures
Cotton - Negotiate between pounds, bales and tonnes
Coffee - Of pounds, bags and tonnes
Sugar - The different measures of sweetness
Corn - Bushels and tonnes, for rye and sorghum too
Grains - The different type of bushels
Oilseed - Crush calculator, and bushels to tonnes
