1. Convert, select, and use measurements within the same system
Conversions within a single measurement system rely on consistent unit relationships. Mastery requires not only memorization but also understanding of multiplicative relationships.
Metric system
The metric system is base-10, meaning each step involves multiplying or dividing by 10, 100, or 1,000.
- Length: 1 kilometer (km) = 1,000 meters (m); 1 meter = 100 centimeters (cm); 1 centimeter = 10 millimeters (mm).
- Mass: 1 kilogram (kg) = 1,000 grams (g); 1 gram = 1,000 milligrams (mg).
- Capacity: 1 liter (L) = 1,000 milliliters (mL).
Example: To convert 4.25 liters into milliliters, multiply 4.25 × 1,000 = 4,250 mL.
U.S. customary system
The U.S. system uses fixed relationships that are less intuitive because they are not powers of 10.
