Celsius to Fahrenheit Converter
This Celsius to Fahrenheit converter changes a temperature in °C into °F. It loads in the temperature category with Celsius as the source and Fahrenheit as the target, so typing a value applies the formula °F = °C × 9/5 + 32 immediately: 0 °C = 32 °F, 100 °C = 212 °F, and 37 °C = 98.6 °F. It is useful for weather reports, cooking and baking conversions, science homework, and device specifications written in metric. A swap button reverses the direction for Fahrenheit to Celsius. Because the calculation runs entirely in JavaScript in your browser, nothing is sent to a server or stored. The result updates as you type.

°C × 9/5 + 32 = °FFrequently asked questions
What is the formula to convert °C to °F? +
Multiply by 9, divide by 5, then add 32: °F = °C × 9/5 + 32. For example, 20 °C = 68 °F.
What are the key reference points? +
Water freezes at 0 °C / 32 °F and boils at 100 °C / 212 °F at standard pressure; normal body temperature is about 37 °C / 98.6 °F.
Can temperatures be negative? +
Yes. The same formula works for negative values, for example −40 °C equals −40 °F.
What unit categories does the converter support? +
This tool converts length, weight, temperature, area, volume, speed, time, data storage, and many more categories.
Can I convert between metric and imperial units? +
Yes. Convert freely between metric (km, kg, liters) and imperial (miles, pounds, gallons) systems, and many other unit systems.
How accurate are the conversions? +
All conversions use precise mathematical factors. Results are displayed with up to 10 decimal places for maximum accuracy.
Does it support currency conversion? +
The tool focuses on physical units. For currency conversion with live exchange rates, a dedicated currency tool is recommended.
