What Is This Tool?

This tool helps users convert values from lux (lx) to meter-candle (m*c), two units that measure illuminance. It provides a simple way to align modern photometric measurements with historical standards and supports various applications in lighting design, photography, and testing.

How to Use This Tool?

  • Enter the illuminance value in lux [lx] in the input field.
  • Select meter-candle [m*c] as the target unit for conversion.
  • Click the convert button to get the equivalent value in meter-candle.
  • View the result instantly, noting that 1 lx equals 1 m*c.

Key Features

  • Converts between lux and meter-candle with a direct one-to-one ratio.
  • Supports measurement standardization between modern and older lighting units.
  • Browser-based and easy to use without any installation.
  • Useful for professionals in lighting design, architecture, and photography.

Examples

  • Convert 100 lux: 100 lx equals 100 meter-candle.
  • Convert 350 lux: 350 lx equals 350 meter-candle.

Common Use Cases

  • Aligning current illumination measurements with historical lighting standards.
  • Calibrating instruments in photography, display testing, and lighting design.
  • Interpreting older photometric and lighting-design literature referencing meter-candle.
  • Ensuring compliance with lighting regulations in indoor and outdoor environments.

Tips & Best Practices

  • Always confirm which unit is preferred in your industry or region before reporting values.
  • Use this converter to maintain consistency when working with both modern and legacy lighting data.
  • Consider the context—lux and meter-candle are numerically equivalent but have different historical usage.
  • Apply this tool to facilitate accurate communication in multidisciplinary projects.

Limitations

  • No numerical adjustment is needed since 1 lux equals 1 meter-candle, but unit preference matters.
  • Meter-candle is largely obsolete, so consult relevant standards before use.
  • Careful interpretation required when working with historical data versus contemporary measurements.

Frequently Asked Questions

What is the difference between lux and meter-candle?
Lux and meter-candle both measure illuminance and are numerically equivalent, but meter-candle is an older unit based on a point source at one meter, while lux is the SI derived unit.

Why convert lux to meter-candle if they are equal?
Converting helps align modern measurements with historical literature and standards that use meter-candle terminology.

Where is this conversion commonly applied?
It is widely used in lighting design, architecture, photography, display manufacturing, and compliance testing.

Key Terminology

Lux [lx]
The SI derived unit of illuminance that measures luminous flux per square metre, weighted according to human daylight visual response.
Meter-candle [m*c]
An older unit of illuminance equal to one lumen per square metre, representing illumination from a point source one candela at one metre distance.
Illuminance
The measure of luminous flux incident on a surface per unit area, indicating the brightness of illumination.
