pound per hour to tonne per hour
Convert pound per hour (lb/h) to tonne per hour (t/h). Use an editable mass flow rate converter, conversion formula, and reference table.
1 lb/h = 0.00045359237 t/h
Conversion formula
One pound per hour equals 0.00045359237 tonne per hour. Multiply your value in pound per hour by this factor to get tonne per hour. For the reverse conversion, divide by the same factor.

About these measurements
Mass flow rate measures mass passing a point per unit time.
The base reference used here is the kilogram per second. One pound per hour is 0.0001259978806 base units; one tonne per hour is 0.2777777778 base units.
Important distinctions
Compound units must match the quantity and dimension. Temperature intervals use size factors rather than temperature offsets. Calorie and BTU entries use the explicit definitions shown.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
Common questions
How do I convert lb/h to t/h?
Multiply the quantity in lb/h by 0.00045359237. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the tonne per hour to pound per hour converter.
