Canadian cups
Canadian cups are units often used in Canada for recipes. One Canadian cup is about 227ml making this unit slightly smaller than the metric cup which is equal to 250 milliliters.
Microliters
Microliters are a unit of volume in the metric system used to measure very small amounts of liquid. One microliter is equal to one millionth of a liter. This tiny unit of measurement is often denoted by the symbol μL. To put it into perspective, a single drop of water is roughly equivalent to about 50 microliters.
