Celsius to Fahrenheit Calculator
Equipment data sheets, NEC ampacity tables, and international standards frequently list temperature limits in Celsius. If your thermometer or weather app reads Fahrenheit, this converter bridges the gap in seconds.
Type a Celsius value and the calculator returns the Fahrenheit and Kelvin equivalents immediately. It accepts negative values, so it works for cold-weather installations as well.
Conversion Formula
°F = °C × 9/5 + 32
Multiply by 1.8, then add 32
For a quick mental shortcut, double the Celsius value and add 30. This gives a rough Fahrenheit estimate that is accurate within a few degrees for moderate temperatures.
Frequently Asked Questions
What is the formula to convert Celsius to Fahrenheit?
Multiply the Celsius value by 9/5 (or 1.8), then add 32. The formula is F = C x 9/5 + 32. For example, 25 degrees C times 1.8 is 45, plus 32 equals 77 degrees F.
What is 0 degrees Celsius in Fahrenheit?
0 degrees Celsius equals 32 degrees Fahrenheit. This is the freezing point of water at standard atmospheric pressure and serves as a key reference point for temperature conversions.
Why are temperature conversions important in electrical work?
Wire ampacity, insulation ratings, and equipment operating ranges are often specified in Celsius in technical standards and NEC tables. If you measure ambient temperature in Fahrenheit, you need to convert to Celsius to apply derating factors correctly and ensure safe installations.
