What Is This Tool?
This unit converter transforms illuminance values measured in lumen per square foot, commonly used in lighting practice, into meter-candle, an older metric unit equivalent to lux. It assists professionals and enthusiasts in accurately translating lighting levels for various applications.
How to Use This Tool?
-
Enter the illuminance value in lumen per square foot (lm/ft^2)
-
Select the input unit as lumen/square foot [lm/ft^2]
-
Choose meter-candle [m*c] as the output unit
-
Click the convert button to get the equivalent meter-candle measurement
-
Review the result and use it for lighting calculations or documentation
Key Features
-
Converts lumen per square foot (lm/ft^2) to meter-candle (m*c) with precise unit matching
-
Supports measurement translation from imperial to metric lighting units
-
Useful for lighting design, photography, horticulture, and historical research
-
Browser-based and easy to use for quick illumination conversions
-
Includes practical examples to guide accurate conversions
Examples
-
5 lm/ft^2 converts to approximately 53.82 m*c
-
0.1 lm/ft^2 converts to about 1.08 m*c
Common Use Cases
-
Checking and specifying indoor lighting levels in offices, classrooms, and retail environments
-
Setting appropriate illumination for photography, stage lighting, and display setups
-
Planning horticultural lighting and protecting sensitive museum or gallery exhibits
-
Interpreting historical lighting data using meter-candle references
-
Calibrating lighting instruments for accuracy in design and testing
Tips & Best Practices
-
Clarify the context and unit standards when reporting illumination values to avoid confusion
-
Use this converter when transitioning between imperial and metric illuminance units
-
Refer to provided examples to verify conversion accuracy
-
Remember that meter-candle and lux are numerically equivalent
-
Note historical usage of meter-candle and prefer lux for contemporary applications
Limitations
-
Meter-candle is largely a historical unit and is less commonly used than lux nowadays
-
Conversion may cause misunderstandings if unit context or lighting standards are unclear
-
This tool does not account for specific lighting conditions besides unit conversion
Frequently Asked Questions
-
What does lumen per square foot measure?
-
It measures illuminance as luminous flux incident on a one-square-foot surface, equivalent to a foot-candle used in lighting.
-
How is meter-candle related to lux?
-
Meter-candle is an older illuminance unit numerically equal to one lux, both representing lumens per square meter.
-
Why convert from lumen/square foot to meter-candle?
-
Converting helps accommodate international lighting standards by translating from imperial to metric measurement units.
Key Terminology
-
Lumen per square foot [lm/ft^2]
-
A measure of illuminance indicating luminous flux over one square foot, equivalent to foot-candle.
-
Meter-candle [m*c]
-
An older illuminance unit equal to one lumen per square metre, numerically the same as lux.
-
Illuminance
-
The measure of luminous flux incident on a surface area, indicating how much light arrives per unit area.
