What Is This Tool?
This converter translates the informal illumination measurement 'flame'—which describes the light from open combustion sources—into the SI derived unit lumen per square meter (lm/m^2), a precise metric commonly used for quantifying illuminance on surfaces.
How to Use This Tool?
-
Enter the value in flames representing the light intensity from an open flame source.
-
Select the conversion to lumen per square meter [lm/m^2].
-
Submit the input to receive the corresponding illuminance value in standardized units.
Key Features
-
Converts informal 'flame' lighting estimates into standardized lumens per square meter.
-
Supports illumination measurement needs across diverse fields like lighting design, safety, and environmental monitoring.
-
Provides direct examples illustrating flame-to-lumen/meter squared conversions.
Examples
-
2 Flames converts to 86.1112833336 lumen per square meter [lm/m^2].
-
0.5 Flame converts to 21.5278208334 lumen per square meter [lm/m^2].
Common Use Cases
-
Converting informal lighting descriptions for scientific or regulatory reporting.
-
Assisting firefighting and safety teams in estimating light levels from open flames.
-
Supporting lighting design standards and measurements in workspaces or public environments.
-
Photography and cinematography requiring precise exposure settings based on illuminance.
-
Horticultural lighting management within greenhouses and growth facilities.
-
Field research in archaeology and anthropology where rough light quantification is needed.
Tips & Best Practices
-
Use this conversion when a rough estimate of open flame illumination needs to be expressed in standardized units.
-
Remember the flame unit is qualitative and can vary with the flame’s characteristics or surroundings.
-
Combine this tool with precise measurement instruments for accurate lighting assessments.
-
Apply conversion results carefully in safety or technical contexts due to the flame unit’s approximate nature.
Limitations
-
Flame is a non-standardized and informal descriptor of light intensity.
-
Conversion results depend on variable flame properties and environmental factors.
-
Luminous flux measurement in lumen per square meter requires specialized instruments, unlike the qualitative flame unit.
Frequently Asked Questions
-
What does the unit 'flame' represent?
-
'Flame' is an informal, non-standardized unit describing the light emitted by an open combustion source such as a candle or torch, commonly used in qualitative contexts.
-
Why convert flame to lumen per square meter?
-
Converting flame to lumen per square meter allows informal or qualitative light descriptions to be expressed as precise, standardized illuminance measurements useful in scientific and technical fields.
-
Is the conversion from flame to lumen per square meter exact?
-
No, because flame is an approximate unit dependent on flame type and environment; therefore, conversion results provide an estimation rather than exact values.
-
Where is lumen per square meter used?
-
Lumen per square meter, equivalent to lux, is widely used for specifying lighting levels in workplaces, photography, horticulture, and safety assessments.
Key Terminology
-
Flame
-
An informal, non-standardized descriptor for light emitted by an open combustion source such as a torch or candle.
-
Lumen per square meter [lm/m^2]
-
The SI derived unit of illuminance representing one lumen of luminous flux evenly distributed over one square meter of surface, equivalent to lux.
-
Illuminance
-
A measure of the amount of visible light striking a surface area, weighted by the human photopic response.
