How to Convert Millicandelas to Candelas
To convert millicandelas to candelas, multiply the luminous intensity by the following conversion ratio: 0.001 candelas/millicandela.
Since one millicandela is equal to 0.001 candelas, you can use this simple formula to convert:
The luminous intensity in candelas is equal to the luminous intensity in millicandelas multiplied by 0.001.
For example, here's how to convert 10 millicandelas to candelas using the formula above.
How Many Candelas Are in a Millicandela?
There are 0.001 candelas in a millicandela, which is why we use this value in the formula above.
Our millicandela to candela calculator automatically converts your luminous intensity measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Millicandelas and candelas are both units used to measure luminous intensity. Keep reading to learn more about each unit.
What Is a Millicandela?
A millicandela is a unit of luminous intensity equal to 1/1,000 of a candela (0.001 cd). Indicator LED brightness unit (0.001 cd). [1]
The millicandela is classified as a metric and SI-compatible unit of luminous intensity. Millicandelas can be abbreviated as mcd; for example, 1 millicandela can be written as 1 mcd.
In the metric system, "milli" is the standard SI prefix for thousandths, or 10⁻³. This makes the millicandela (mcd) a convenient decimal multiple of the candela (cd).
In practice, millicandelas (mcd) are widely used across fine-tolerance laboratory, analytical, and micro-scale luminous intensity measurements within SI metric workflows, engineering documentation, and technical data sheets.
What Is a Candela?
Fundamental SI base unit of luminous intensity. It serves as a primary reference unit for measuring luminous intensity across scientific and practical applications. [2]
The candela is classified as an International System of Units (SI) unit of luminous intensity. Candelas can be abbreviated as cd; for example, 1 candela can be written as 1 cd.
As the primary coherent reference unit for luminous intensity in this category, all other luminous intensity units are mathematically anchored to the candela (cd).
In practice, candelas (cd) are widely used across standard luminous intensity applications within International System of Units (SI) workflows, engineering documentation, and technical data sheets.
When converting luminous intensity between millicandelas (mcd) and candelas (cd), keep full floating-point precision (1 mcd = 0.001 cd; 1 cd = 1,000 mcd) during intermediate calculations and round only the final candela figure to match your instrument tolerance.
