Temperature Conversion Calculator

Use our temperature converter to accurately calculate the temperature in different units of measurement, like Celsius (C), Fahrenheit (F) and Kelvin (K).

Precise temperature measurements are required in multiple industries, with the exact unit of measurement sometimes differing from industry to industry, or country to country. Our handy temperature conversion calculator takes the difficult equations out of it and gives you the temperature measurement you need instantly. Just input a value and measurement unit and select your desired output units.

Wondering how temperature conversions are calculated?

Take a look below at the temperature conversion formula for each common measurement unit:  

  • Celsius to Fahrenheit: F = (9/5 x C) + 32
  • Fahrenheit to Celsius: C = (F- 32) x 5/9
  • Celsius to Kelvin: K = C + 273.15
  • Kelvin to Celsius: C = K - 273.15
  • Fahrenheit to Kelvin: K = (F – 32) x 5/9 + 273.15
  • Kelvin to Fahrenheit: F = (K – 273.15) x 9/5 + 32

Digital Thermometers

A digital thermometer is a scientific tool which is used to measure temperature, using a probe to work out the temperature and a digital screen to present the numerical reading.  

Temperature Probes

Temperature probes such as thermistors, thermocouples and PT100 are devices that are used to measure the temperature of air, liquids and surfaces.

Infrared Thermometers

Infrared Thermometers

Sometimes referred to as simply IR thermometers, infrared thermometers work by measuring the thermal radiation that an object emits, meaning they can be used from a distance and without direct contact with the object.
