A decimal-based system of measurement that uses units increasing or decreasing by powers of 10. It is the most widely used system in science and medicine today.
Key Features:
- Easy to convert (just move the decimal point).
- Uses basic units like grams (g) for weight, liters (L) for volume, and meters (m) for length.
Metric System
An older system of measurement that originated in the United Kingdom. It uses grains, drams, and ounces for weight and volume, and often works with fractions.
Key Features:
- More complex because of fractions (like 1/2, 1/4).
- Not based on units of 10.
- Rarely used today but still seen in some older prescriptions.
Apothecary System
A system based on everyday items (like teaspoons and cups) that is used by the general public for home medication dosing.
Key Features:
- Simple and familiar to most people.
- Less precise compared to Metric and Apothecary systems.
- Often used in instructions for patients taking medicine at home.
