What Is This Tool?
This online converter transforms heat flux density measurements from dyne/hour/centimeter, a nonstandard CGS-derived unit, into Btu (IT)/second/square foot, an Imperial-based unit used for high heat flux applications. It facilitates interpreting legacy CGS-based heat flux data and applying it in modern thermal analysis contexts.

Tips & Best Practices
-
Verify that the original heat flux data is accurately recorded in dyne/hour/centimeter before conversion
-
Use the converter to translate legacy CGS units to more practical Imperial units for high heat flux scenarios
-
Be mindful of the extremely small values resulting from conversion to Btu (IT)/second/square foot
-
Cross-check converted results when integrating with modern thermal analyses or design criteria
Limitations
-
Dyne/hour/centimeter represents very small heat fluxes, while Btu (IT)/second/square foot is designed for much larger values, leading to very small decimal outputs
-
Nonstandard and obsolete nature of dyne/hour/centimeter requires careful context consideration
-
Differences in unit systems (CGS vs Imperial/Non-SI) mean that precision and applicability depend on correct conversion usage
Frequently Asked Questions
-
What does dyne/hour/centimeter measure?
-
It measures heat flux density as one dyne of force per hour per centimeter, equivalent to energy flux per area in old CGS units.
-
Why convert dyne/hour/centimeter to Btu (IT)/second/square foot?
-
Converting allows use of small-scale CGS-based heat flux data in contexts requiring larger Imperial units, such as fire testing or industrial thermal analyses.
-
Are conversions between these units precise?
-
Conversions follow a defined conversion rate, but very small resulting values and differences in unit systems mean precision depends on proper context and usage.
Key Terminology
-
Dyne/hour/centimeter
-
A CGS-derived unit of heat flux density representing one dyne of force per hour per centimeter of length, equivalent to erg per second per square centimeter.
-
Btu (IT)/second/square foot
-
A non-SI unit of heat flux density representing one British thermal unit (International Table) transferred per second across one square foot.
-
Heat Flux Density
-
A measurement of thermal power transferred per unit surface area, indicating energy flow intensity.
