How to Convert Candelas per Sq. Meter to Lamberts
To convert candelas per sq. meter to lamberts, multiply the luminance by the following conversion ratio: 0.000314159 lamberts/candela per square meter.
Since one candela per square meter is equal to 0.000314159 lamberts, you can use this simple formula to convert:
The luminance in lamberts is equal to the luminance in candelas per sq. meter multiplied by 0.000314159.
For example, here's how to convert 10 candelas per sq. meter to lamberts using the formula above.
How Many Lamberts Are in a Candela per Square Meter?
There are 0.000314159 lamberts in a candela per square meter, which is why we use this value in the formula above.
Our candela per square meter to lambert calculator automatically converts your luminance measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Candelas per Sq. Meter and lamberts are both units used to measure luminance. Keep reading to learn more about each unit.
What Is a Candela per Square Meter?
SI display brightness and luminance unit (1 nit = 1 cd/m²). It serves as a primary reference unit for measuring luminance across scientific and practical applications. [1]
The candela per square meter is classified as an International System of Units (SI) unit of luminance. Candelas per Sq. Meter can be abbreviated as cd/m²; for example, 1 candela per square meter can be written as 1 cd/m².
As the primary coherent reference unit for luminance in this category, all other luminance units are mathematically anchored to the candela per square meter (cd/m²).
In practice, candelas per sq. meter (cd/m²) are widely used across standard luminance applications within International System of Units (SI) workflows, engineering documentation, and technical data sheets.
What Is a Lambert?
A lambert is a unit of luminance equal to 3,183.0988618 candelas per sq. meter (cd/m²), the base unit for luminance. Equal to (10,000/π) ≈ 3,183.099 cd/m². [2]
The lambert is classified as a metric and SI-compatible unit of luminance. Lamberts can be abbreviated as L; for example, 1 lambert can be written as 1 L.
When working with lamberts (L) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, lamberts (L) are widely used across large-scale industrial, bulk, and macro-level luminance specifications within SI metric workflows, engineering documentation, and technical data sheets.
When converting luminance between candelas per sq. meter (cd/m²) and lamberts (L), keep full floating-point precision (1 cd/m² = 0.000314159 L; 1 L = 3,183.0988618 cd/m²) during intermediate calculations and round only the final lambert figure to match your instrument tolerance.
