What Is This Tool?

This converter transforms heat flux density values from watt per square inch (W/in^2), an imperial-based unit measuring power per square inch, into erg per hour per square millimeter, a CGS-derived metric unit used in specialized laboratory and scientific applications.

How to Use This Tool?

  • Enter the heat flux density value in watts per square inch.
  • Select the conversion to erg per hour per square millimeter.
  • Submit the value to view the equivalent in erg/hour/mm² based on the precise conversion factor.

Key Features

  • Converts heat flux density units from W/in² to erg/hour/mm² quickly
  • Supports conversion between imperial-area based and CGS-derived metric units
  • Ideal for applications needing cross-system unit translation in thermal engineering and scientific research

Examples

  • 2 W/in² converts to 111600223.29 erg/hour/mm²
  • 0.5 W/in² converts to 27900055.82 erg/hour/mm²

Common Use Cases

  • Measuring power density of focused heat sources like lasers on small surfaces
  • Thermal testing and design of electronics and semiconductor components
  • Reporting thin-film or coating heat transfer experiments in laboratory settings using CGS units
  • Comparing legacy or astrophysical radiative flux data expressed in ergs per hour per square millimeter

Tips & Best Practices

  • Carefully manage unit differences between imperial and CGS systems to avoid confusion
  • Use precise values to minimize rounding errors due to the large conversion factor
  • Confirm unit consistency when interpreting results, especially in small-scale heat flux analyses

Limitations

  • Unit system differences can cause confusion without careful handling
  • Large conversion factor requires attention to numerical precision
  • Erg/hour/square millimeter is uncommon in modern SI-based work, potentially reducing direct applicability

Frequently Asked Questions

What does watt per square inch measure?
Watt per square inch measures heat flux density as power transferred or emitted per unit area of one square inch, primarily in imperial units.

When would I use erg per hour per square millimeter?
Erg per hour per square millimeter is used in laboratory and scientific contexts, especially when dealing with small-area heat transfer using CGS energy units.

Why is the conversion factor so large?
The conversion involves changing from imperial to CGS units and adjusting the energy, time, and area scales, which results in a large numerical factor.

Key Terminology

Watt per square inch [W/in²]
