Cubic Millimeters
A cubic millimeter is the volume of a cube 1 millimeter on each side, so 1,000 of them make a cubic centimeter. It is the same as a microliter, and a drop of water is roughly 50 cubic millimeters.
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.
