About Unit Conversion
Conversion calculators are essential tools for engineering, cooking, science, and everyday life. Different regions use different measurement systems (Imperial vs. Metric), making conversion necessary.
Common Conversions
- Length: 1 inch = 2.54 cm, 1 mile = 1.609 km
- Weight: 1 kg = 2.20462 lbs, 1 lb = 16 oz
- Volume: 1 gallon = 3.785 liters, 1 liter = 1000 ml
- Temperature: F = (C × 9/5) + 32
Why Metric?
The metric system (SI) is used by almost every country in the world except the United States, Liberia, and Myanmar. It is base-10, making calculations much easier (e.g., 1000 meters in a kilometer). The Imperial system is more complex but remains standard in the US for everyday measurements like miles, feet, and gallons.
