Measuring tips
Weights are for dry, uncooked grains unless the name says cooked. Most grains roughly double or triple in volume when cooked.
The tables use a US cup of 236.6 ml. A metric cup (250 ml, used in Australia, Canada and New Zealand) of rolled oats weighs about 95 g. Switch the cup size in the converter above.
Weights are averages from published kitchen weight charts. Brand, humidity and how you fill the cup can change them by 5–10%, so for baking a scale is always more accurate.
