Instantly convert between metric, imperial, and digital storage units (Length, Weight, Temperature, Area, Volume, and Bytes).
Converting units manually can lead to costly mathematical errors in web development, graphic design, international shipping, and recipes. Our free online Units Converter calculates all matching units simultaneously as you type.
| Category | From Unit → To Unit | Mathematical Formula |
|---|---|---|
| Length | Meters → Feet | Feet = Meters × 3.28084 |
| Length | Inches → Centimeters | Centimeters = Inches × 2.54 |
| Weight | Kilograms → Pounds | Pounds = Kilograms × 2.20462 |
| Temperature | Celsius → Fahrenheit | °F = (°C × 1.8) + 32 |
| Data Storage | Gigabytes → Megabytes (Binary) | MB = GB × 1024 |
To convert Celsius (°C) to Fahrenheit (°F), multiply the Celsius temperature by 9/5 (or 1.8) and add 32: °F = (°C × 1.8) + 32. To convert Fahrenheit back to Celsius, subtract 32 and divide by 1.8: °C = (°F - 32) ÷ 1.8.
Hard drive and SSD manufacturers use the base-10 decimal standard (1 KB = 1,000 Bytes, 1 MB = 1,000 KB, 1 GB = 1,000 MB). Computer operating systems (like Windows) calculate file sizes using the base-2 binary standard (1 KiB = 1,024 Bytes, 1 MiB = 1,024 KiB, 1 GiB = 1,024 MiB). This is why a 1 TB hard drive reports approximately 931 GB in Windows.
1 kilogram equals exactly 2.20462 pounds (lbs). To convert kilograms to pounds, multiply by 2.20462. To convert pounds to kilograms, divide by 2.20462 (or multiply by 0.453592).
1 inch is defined internationally as exactly 25.4 millimeters (mm). To convert mm to inches, divide by 25.4. To convert inches to mm, multiply by 25.4.
