International System of Units (SI)

The SI, or decimal system of measurement, is used in pharmacy and the pharmaceutical industry.
It's built on seven base units:
- Length: meter (m)
- Mass: kilogram (kg)
- Time: seconds (s)
- Electric current: ampere (A)
- Temperature: kelvin (K)
- Amount of substance: mole (mol)
- Luminous intensity: candela (cd)
To convert an SI unit to a smaller unit, move the decimal point one place to the right.
To convert an SI unit to a larger unit, move the decimal point one place to the left.

Weight

Weight measures the gravitational force acting on a body.
It's directly proportional to the body's mass.

Systems of Measurement
