About Pound per foot-hour (lb/(ft·hr))
An imperial dynamic-viscosity unit used in some US process-engineering and HVAC contexts where timescales are naturally in hours rather than seconds. 1 lb/(ft·hr) ≈ 4.134 × 10⁻⁴ Pa·s. Found in some heat-transfer coefficient calculations and older US chemical engineering handbooks, particularly for gas-phase viscosity at industrial-operating conditions.
About Pound per foot-second (lb/(ft·s))
An imperial dynamic-viscosity unit (using pound-mass). Primarily encountered in US petroleum engineering, legacy ASME fluid-mechanics textbooks, and HVAC calculations where engineers prefer consistent US customary units throughout. 1 lb/(ft·s) ≈ 1.488 Pa·s. Most modern US engineering has migrated to centipoise or Pa·s, so this unit is most useful for interpreting older specifications and technical literature.

Frequently Asked Questions
How do I convert Pounds per foot-hour to Pounds per foot-second?
An imperial dynamic-viscosity unit used in some US process-engineering and HVAC contexts where timescales are naturally in hours rather than seconds. To convert Pounds per foot-hour to Pounds per foot-second, multiply by 2.7778e-4. For example, 25 lb/(ft·hr) equals 0.00694446 lb/(ft·s).
How many Pounds per foot-second are in 1 Pound per foot-hour?
There are 0.000277779 Pounds per foot-second in 1 Pound per foot-hour.
How many Pounds per foot-hour are in 1 Pound per foot-second?
There are 3599.99 Pounds per foot-hour in 1 Pound per foot-second.
What is the formula for Pound per foot-hour to Pound per foot-second conversion?
The formula is: multiply by 2.7778e-4. This means 1 lb/(ft·hr) = 0.000277779 lb/(ft·s).
Is a Pound per foot-hour bigger than a Pound per foot-second?
Yes. One Pound per foot-hour is larger than one Pound per foot-second because 1 lb/(ft·hr) equals 0.000277779 lb/(ft·s), which is less than 1.
When do you need to convert between Pounds per foot-hour and Pounds per foot-second?
An imperial dynamic-viscosity unit (using pound-mass). Pound per foot-hour and Pound per foot-second are both dynamic viscosity units, so conversion comes up whenever one source of information uses one unit and another uses the other — a classic cross-reference challenge in engineering, trade, travel, and everyday life.
