How to choose the correct unit converter
Start with the quantity you are measuring: distance, mass, temperature, capacity, area, speed, storage or time. Then choose the starting unit and destination unit. A conversion changes the unit used to express a quantity, not the underlying quantity itself.
Common conversion examples
- Length: 1 inch = exactly 2.54 centimeters.
- Mass: 1 kilogram ≈ 2.20462 pounds.
- Temperature: °F = (°C × 9/5) + 32.
- Speed: 1 kilometer per hour ≈ 0.621371 miles per hour.
- Digital storage: 1 GB = 1,000 MB; 1 GiB = 1,024 MiB.
Always check whether a converter uses US customary or imperial units, and whether digital storage uses decimal or binary definitions.
