Metric vs. Imperial Measurement Systems
The Metric System (SI) is the standard decimal system of measurement used worldwide based on multiples of ten (meters, kilograms, liters). In contrast, the Imperial System and US Customary System use historical units such as inches, feet, yards, miles, pounds, and gallons.
| Measurement | Metric (SI) Standard | US / Imperial Standard | Exact Conversion Ratio |
|---|---|---|---|
| Length | Meter (m) | Foot (ft) | 1 m = 3.28084 ft / 1 ft = 0.3048 m |
| Mass / Weight | Kilogram (kg) | Pound (lb) | 1 kg = 2.20462 lb / 1 lb = 0.453592 kg |
| Volume | Liter (L) | US Gallon (gal) | 1 gal (US) = 3.78541 L |
| Temperature | Celsius (°C) | Fahrenheit (°F) | °F = (°C × 9/5) + 32 |
