Temperature Unit Conversions

Celsius To Fahrenheit

fahrenheit = (celsius * 9 / 5) + 32

Fahrenheit To Celsius

celsius = (fahrenheit-32) * 5 / 9

Kelvin Conversions

kelvin = celsius + 273.15
celsius = kelvin - 273.15


Pressure Unit Conversions

Note: Millibars are also known as hectopascals

Inches To Millibars

millibars = inches * 33.8653

Millibars To Inches

inches = millibars / 33.8653

Kilopascal Conversions

millibars = kilopascals * 10
kilopascals = millibars / 10
