How do you convert Celsius to Fahrenheit?
Multiply by 9/5 (or 1.8) and add 32. So 20 degrees C = (20 multiplied by 1.8) + 32 = 68 degrees F. Our converter handles this automatically for all temperature units including Kelvin.

Helpful questions
What's the difference between metric and imperial?
Metric (SI) uses meters, kilograms, and liters with base-10 scaling. Imperial uses feet, pounds, and gallons with less systematic conversions. Most of the world uses metric; the US primarily uses imperial.
How accurate are the conversions?
The converter uses standard conversion factors and rounded output for everyday use. Review critical engineering, scientific, legal, or safety-sensitive work against authoritative sources.
Can I convert between categories?
Each category converts within its own unit family. You can't directly convert kilograms to meters - they measure different properties. Select the appropriate category tab for your conversion needs.
