What Is This Tool?

This online converter tool enables you to convert illuminance values from meter-candle (m*c), an older unit of illuminance, to lumen per square meter (lm/m²), the modern SI standard equivalent to lux. It helps interpret and apply historical lighting data within contemporary lighting design and measurement contexts.

How to Use This Tool?

  • Enter the value in meter-candle (m*c) that you want to convert
  • Select meter-candle as the input unit and lumen per square meter as the output unit
  • Click the convert button to view the equivalent illuminance in lumen/square meter
  • Use the result to compare or standardize lighting measurements

Key Features

  • Converts meter-candle values directly to lumen/square meter with a one-to-one equivalence
  • Browser-based and easy to use for quick illumination unit conversions
  • Supports accurate translation of older lighting measurements to modern standards
  • Useful for applications in lighting design, photography, and horticulture

Examples

  • 200 meter-candle equals 200 lumen per square meter
  • 500 meter-candle corresponds to 500 lumen per square meter

Common Use Cases

  • Converting historical photometry data using metre-candle units to contemporary SI units
  • Specifying and verifying lighting levels in offices, classrooms, and public spaces
  • Calibrating and interpreting illuminance measurements for photography and display testing
  • Controlling light intensity on plants in horticultural and greenhouse settings

Tips & Best Practices

  • Always verify the unit labels when working with historical data to ensure accurate interpretation
  • Use this converter to standardize lighting data before applying it to modern lighting design standards
  • Consider calibration differences in measurement devices even if units are equivalent
  • Apply the results to support lighting assessments in workspace, photography, and horticultural applications

Limitations

  • The converter applies a direct one-to-one conversion since meter-candle and lumen per square meter are equivalent units
  • Care is needed when interpreting historical illuminance data to align with modern lighting standards
  • Measurement method differences and calibration variations may influence reported illuminance values

Frequently Asked Questions

What is the meter-candle unit?
Meter-candle is an older illuminance unit equal to one lumen per square meter, representing the illuminance from a point source of one candela at one meter distance. It is numerically equivalent to the lux.

Is there any numerical difference when converting meter-candle to lumen per square meter?
No, converting meter-candle to lumen per square meter does not involve a numerical change because both units are equal in value.

Why is it important to convert meter-candle to lumen per square meter?
Conversion helps translate older illuminance measurements into the modern SI standard, ensuring accurate and standardized lighting assessment, design, and calibration of instruments.

Key Terminology

Meter-candle [m*c]
An older illuminance unit equal to one lumen per square meter, representing the illuminance from a one candela point source at one meter distance; equivalent to the lux.
Lumen per square meter [lm/m^2]
The SI derived unit of illuminance, defined as one lumen of luminous flux incident uniformly on one square meter of surface; equivalent to the lux.
Illuminance
The amount of visible light falling on a surface, weighted by the human eye’s photopic response.
