What Is This Tool?
This converter transforms heat flux density values from watts per square meter (SI unit) to ergs per hour per square millimeter (a CGS-derived unit). It's designed to support measurements used in micro-scale experiments, legacy data, and astrophysical contexts.
How to Use This Tool?
- Enter the heat flux density value in watt/square meter (W/m²).
- Select watt/square meter as the input unit and erg/hour/square millimeter as the output unit.
- Click the convert button to obtain the equivalent value in erg/hour/square millimeter.
Key Features
- Converts heat flux density between watt/square meter and erg/hour/square millimeter.
- Supports unit conversions involving SI and CGS-based energy units over different surface areas.
- Offers easy online access for quick calculations without additional tools.
- Facilitates comparisons in laboratory, microelectronics, and astrophysics settings.
Examples
- 2 W/m² converts to 72000 erg/hour/mm².
- 0.5 W/m² converts to 18000 erg/hour/mm².
Common Use Cases
- Specifying solar irradiance for photovoltaic and solar resource assessments.
- Thermal characterization of microelectronic components and sensors per square millimeter.
- Reporting heat transfer in thin-film and coating laboratory experiments.
- Analyzing historical or astrophysical radiative-flux data expressed in CGS units.
Tips & Best Practices
- Ensure correct unit selection before converting values to avoid errors.
- Use this tool for small-area and CGS-unit contexts to maintain consistency.
- Verify dimensional analysis when mixing CGS and metric units in calculations.
- Check converted results especially when integrating with large-scale engineering data.
Limitations
- The erg/hour/square millimeter unit mixes CGS energy units with metric time and area units, requiring careful interpretation.
- Small surface area units used may complicate comparisons with large-scale heat flux expressed in W/m².
Frequently Asked Questions
