Understanding Temperature Conversions

Temperature is often recorded in either Celsius (°C) or Fahrenheit (°F), depending on region or equipment. Converting between the two is essential in metallurgy, welding, thermal treatments, and even daily life when comparing technical specs.

Formula: Celsius to Fahrenheit

Multiply the Celsius value by 9/5 and add 32.

Fahrenheit = (Celsius × 9/5) + 32

Formula: Fahrenheit to Celsius

Subtract 32 from the Fahrenheit value, then multiply by 5/9.

Celsius = (Fahrenheit - 32) × 5/9

Application Example

When welding stainless steel, preheat temperatures in °C may need conversion if your machine or chart is in °F. This calculator ensures you're setting the correct range every time.
