What Is This Tool?
This unit converter allows you to transform power measurements from deciwatt (dW), a small electrical power unit, to Btu (th)/second (Btu (th)/s), a thermal power unit. It helps relate electrical power to heat transfer rates used in various engineering and HVAC contexts.
How to Use This Tool?
-
Enter the power value in deciwatts (dW) you wish to convert.
-
Select deciwatt as the input unit and Btu (th)/second as the output unit.

Tips & Best Practices
-
Ensure steady-state conditions when applying the conversion to avoid errors from transient dynamics.
-
Double-check unit selections before converting to maintain accuracy.
-
Use the converter for small power values typical to deciwatt scales to minimize rounding effects.
-
Understand that different Btu definitions might influence precision in certain contexts.
Limitations
-
Conversion assumes constant power and does not consider dynamic thermal changes.
-
Small deciwatt values may cause rounding discrepancies after conversion.
-
Precision can be affected by variations between thermochemical and other Btu unit definitions.
Frequently Asked Questions
-
What does one deciwatt represent?
-
One deciwatt equals one tenth of a watt (0.1 W) and is used to measure small power levels.
-
What is Btu (th)/second used for?
-
Btu (th)/second measures heat transfer rate and is commonly applied in HVAC system ratings and thermal energy evaluations.
-
Can I use this converter for dynamic thermal power calculations?
-
No, the converter is intended for steady-state power and does not account for transient or dynamic thermal changes.
Key Terminology
-
Deciwatt (dW)
-
A power unit equal to one tenth of a watt, used for small electrical power levels.
-
Btu (th)/second [Btu (th)/s]
-
A unit measuring the rate of heat transfer, representing one thermochemical British thermal unit per second.
-
Steady-state power
-
Power that remains constant over time without transient fluctuations.
