Speed, temperature and flow converter.
Convert km/h and mph, Celsius/Fahrenheit/Kelvin, LPM/GPM and CFM/m³ per hour.
Speed, temperature and flow converter inputs
GPM is US gallons per minute. Temperature conversion uses the Celsius scale you enter; Kelvin must remain at or above absolute zero for a physically meaningful temperature.
Method: Temperature uses its offset formula; speed and flow convert through SI bases. US gallons are used for GPM unless the selected label says otherwise.
Inputs used: Speed = 100 km/h; Temperature = 20 °C; Liquid flow = 10 LPM; Air flow = 100 CFM
Assumptions: The result uses the values, units and options shown in the input snapshot.
Scope and warnings: GPM is US gallons per minute. Temperature conversion uses the Celsius scale you enter; Kelvin must remain at or above absolute zero for a physically meaningful temperature. Rounding and excluded real-world terms can make an external result differ.
How this speed, temperature and flow converter works
Temperature uses its offset formula; speed and flow convert through SI bases. US gallons are used for GPM unless the selected label says otherwise.
A worked example
20 °C is 68 °F and 293.15 K; 1 CFM is about 1.699 m³/h.
Why does temperature not scale like length?
Celsius and Fahrenheit have both different sized degrees and different zero points, so conversion needs an offset.
Calculations run on your device. Review your results before exporting or sharing them.
Temperature needs an offset formula
Celsius, Fahrenheit and Kelvin use different zero points. Speed and flow values convert through their own bases and should not be mixed with energy or volume totals.
US GPM is shown for liquid flow. Air-flow measurements, density, temperature and pressure can affect real system performance beyond a unit conversion.
