Temperature Conversion

Temperature cannot be converted with simple multiplication — it requires offset formulas. Celsius to Fahrenheit: °F = (°C × 9/5) + 32. Fahrenheit to Celsius: °C = (°F − 32) × 5/9. Celsius to Kelvin: K = °C + 273.15. Absolute zero is −273.15°C = −459.67°F = 0K.

Digital Storage Conversion

Convert between bits, bytes, kilobytes (KB), megabytes (MB), gigabytes (GB), and terabytes (TB). Note: 1 KB = 1,024 bytes (binary), but storage manufacturers often use 1 KB = 1,000 bytes (decimal). Our converter uses the binary standard.
