How to Use This Calculator
Enter Celsius
Provide the temperature in °C directly from your data source.
Read Fahrenheit
The converter applies the linear formula °F = (°C × 9/5) + 32 instantly.
Use the result
Drop the °F value into thermostats, recipes, or status updates for Fahrenheit audiences.
Formula
°F = (°C × 9/5) + 32
°C = (°F − 32) × 5/9
The temperature difference between scales is linear: a 1 °C change equals 1.8 °F.
Use the formula breakdown to confirm the calculation logic or perform the conversion manually if needed.
Full Description
Celsius and Fahrenheit are both linear temperature scales with different zero points and increments. Knowing the conversion helps when interpreting weather forecasts, oven settings, or medical guidelines across regions.
The formula multiplies by 1.8 (9/5) and adds 32 to account for the offset where water freezes at 0 °C but 32 °F.
For quick estimates, doubling the °C and adding 30 comes close, but this tool gives precise results every time.
Frequently Asked Questions
Is the conversion reversible?
Yes. Use °C = (°F − 32) × 5/9 to convert Fahrenheit back to Celsius.
Can I convert decimals?
Absolutely. The converter handles fractional temperatures common in science and cooking.
Why add 32?
Because the Fahrenheit scale’s zero is 32 degrees below the Celsius freezing point of water.
Does this relate to Kelvin?
Kelvin adds 273.15 to Celsius. Use the general Celsius converter when you need Kelvin as well.
