What does 1 millijoule/second represent in terms of power?

1 millijoule/second is equal to 0.001 joules per second or 0.001 watt, representing a small amount of power.

Why convert millijoule/second to Btu (th)/hour?

This conversion helps express low-power energy transfer in units commonly used for heating, cooling, and HVAC applications.

Is this converter suitable for high-power conversions?

No, because millijoule/second applies to very low power ranges and may not be practical for high-power systems using Btu (th)/hour.
