Math & Numbers
Convert mass flow rate between kg/s (kilograms per second, SI base), lb/h (pounds per hour, 1 lb = 0.45359237 kg), and t/h (tonnes per hour, 1 t = 1000 kg). Converts via kg/s to the target unit and also lists the equivalent value in all three units for reference. Used for boiler feedwater, chemical dosing, fuel consumption, and compressed-gas metering.
Call this tool from your code in three languages.
