What Is This Tool?
This converter transforms power measurements from millijoule per second (mJ/s) into the imperial unit foot pound-force per hour (ft·lbf/hr). It is useful for converting low-power readings used in microelectronic and optical systems into legacy imperial units common in mechanical engineering and historical documentation.

Tips & Best Practices
-
Ensure unit selections match the measurement context to prevent errors
-
Use the converter primarily for low power values due to practical unit ranges
-
Be cautious when combining SI and imperial measurements to avoid misinterpretation
-
Refer to examples to validate your calculations
-
Recognize that foot pound-force per hour is a non-SI unit and may introduce rounding differences
Limitations
-
Foot pound-force per hour is a non-SI unit that may cause less precise results compared to SI units
-
Conversion rate is most suitable for very small power values; not ideal for high power levels
-
Base unit differences between the SI and imperial systems require careful use in mixed environments
-
Rounding errors can occur when converting small values between units
Frequently Asked Questions
-
What does millijoule per second measure?
-
Millijoule per second measures power, representing one thousandth of a joule transferred or converted per second, commonly used for low-power systems.
-
Why convert millijoule per second to foot pound-force per hour?
-
Converting to foot pound-force per hour helps translate low-power readings into imperial units useful for legacy equipment and historical engineering documentation.
-
Are there limitations when using foot pound-force per hour units?
-
Yes, it is a non-SI unit with possible rounding errors and may be less precise, especially when used for higher power values or in mixed unit scenarios.
Key Terminology
-
Millijoule per second (mJ/s)
-
A unit of power equal to one thousandth of a joule transferred or converted every second, representing low-power rates often used in microelectronics.
-
Foot pound-force per hour (ft·lbf/hr)
-
A non-SI unit of power representing the energy transferred by one foot-pound-force of work performed each hour, used in legacy imperial measurements.
-
Power
-
The rate at which energy is transferred, converted, or dissipated over time.
