Quantities and measurement – B1–C1

This B1-C1 set of 22 words spans both everyday and scientific ways of expressing quantity: stack, heap, chunk and crumb let you talk about amounts with nuance, while millimetre, micrometre and poise are precise units from scientific texts. You'll understand a medicine dose, a spray or a teaspoon on a label, work out a fraction or a nought in a maths problem, and recognize traditional British units like pint and acre. Billion and ton cover huge quantities, while armful and leash open up rarer, more vivid collective words.
