What Is This Tool?

This unit converter transforms light intensity described in flames, an informal and non-standard photometric unit, into watts per square centimeter at 555 nm, a radiometric measure of irradiance at a specific wavelength relevant for photopic vision. It aids in converting rough visual estimates of illumination into standardized, quantifiable data.

How to Use This Tool?

  • Enter the numeric value representing illumination in flames
  • Select the target unit watt/sq. cm at 555 nm for conversion
  • Click the convert button to obtain the corresponding radiometric irradiance
  • Use the converted value for scientific, safety, or calibration purposes

Key Features

  • Converts 'flame' unit to watt/sq. cm at 555 nm for precise irradiance measurement
  • Supports applications in lighting design, vision science, and safety testing
  • Browser-based and easy to use with simple input and conversion process
  • Provides quantitative results from qualitative visual light descriptors
  • Focuses on the photopic luminous efficiency reference wavelength of 555 nm

Examples

  • 5 Flames converts to 0.0000315195 Watt/sq. cm (at 555 nm)
  • 10 Flames converts to 0.0000630390 Watt/sq. cm (at 555 nm)

Common Use Cases

  • Converting informal flame-based light descriptions into scientific radiometric units
  • Calibrating light sources and photometers using a standard irradiance measurement
  • Conducting vision science and psychophysics experiments at the photopic peak wavelength
  • Evaluating photobiological safety exposure levels for green optical sources
  • Contextualizing historical or fieldwork lighting in archaeology and anthropology

Tips & Best Practices

  • Use this tool when precise quantitative data is needed from qualitative flame descriptions
  • Be aware that 'flame' is subjective and conversions are approximate
  • Consider environmental and source variations that affect flame-based illumination
  • Apply this conversion specifically for monochromatic light at 555 nm wavelength
  • Complement this tool with measurements from calibrated photometric equipment when possible

Limitations

  • 'Flame' is not a standardized unit and is subjective by nature
  • Conversion depends on approximate equivalences and variable flame conditions
  • Results apply only to 555 nm wavelength, not broadband or other spectra
  • Environmental factors and fuel types influence measurement accuracy
  • Precision is limited due to informal and qualitative origin of the 'flame' unit

Frequently Asked Questions

What does the unit 'flame' represent in illumination measurement?
'Flame' is an informal, non-standard unit describing light from open combustion sources like candles or torches. It provides a qualitative estimate rather than a precise measurement.

Why convert from flame to watt per square centimeter at 555 nm?
Converting flame to this radiometric unit enables quantifiable measurement of radiant power at a wavelength relevant to human photopic vision, useful in scientific and safety contexts.

Can this conversion be applied to light sources other than flames?
This conversion is specific to the flame unit and irradiance at 555 nm wavelength, and may not be accurate for broadband or different spectral lighting sources.

How does environmental condition affect the conversion accuracy?
Factors such as flame size, fuel type, and surrounding environment impact the flame's irradiance, making precise conversions approximate.

Is 'flame' a standardized photometric unit?
No, 'flame' is not standardized and is mainly used informally or historically to describe lighting levels qualitatively.

Key Terminology

Flame
An informal descriptor of light emitted by open combustion sources, not standardized and used qualitatively.
Watt/sq. cm (at 555 nm)
A radiometric unit measuring radiant power per unit area specifically at 555 nm wavelength, relevant for photopic vision.
Illuminance
The measure of luminous flux incident on a surface, often calculated by converting monochromatic irradiance to lux.
