A guide to units and measurements

Understand the difference between mass, volume, and device markings.

Mass and volume are different

Milligrams and micrograms describe mass. Milliliters describe volume. A concentration connects the two.

Understand the scale

On a U-100 scale, 100 marked units correspond to one milliliter. These markings are not interchangeable with the biological activity units of a substance.

Check your assumptions

Always confirm the device scale, the stated concentration, and the units in your source. A calculator can only be as reliable as its inputs.
