How to Convert Kilocandelas per Square Meter to Lamberts
To convert kilocandelas per square meter to lamberts, multiply the luminance by the following conversion ratio: 0.3141593 lamberts/kilocandela per square meter.
Since one kilocandela per square meter is equal to 0.3141593 lamberts, you can use this simple formula to convert:
The luminance in lamberts is equal to the luminance in kilocandelas per square meter multiplied by 0.3141593.
For example, here's how to convert 5 kilocandelas per square meter to lamberts using the formula above.
How Many Lamberts Are in a Kilocandela per Square Meter?

What Is a Kilocandela per Square Meter?
A kilocandela per square meter is a unit of luminance equal to 1,000 candelas per sq. meter (cd/m²), the base unit for luminance. Equal to 1,000 nits (cd/m²). [1]
The kilocandela per square meter is classified as a metric and SI-compatible unit of luminance. Kilocandelas per Square Meter can be abbreviated as kcd/m²; for example, 1 kilocandela per square meter can be written as 1 kcd/m².
In the metric system, "kilo" is the standard SI prefix for thousands, or 10³. This makes the kilocandela per square meter (kcd/m²) a convenient decimal multiple of the candela per square meter (cd/m²).
In practice, kilocandelas per square meter (kcd/m²) are widely used across large-scale industrial, bulk, and macro-level luminance specifications within SI metric 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 kilocandelas per square meter (kcd/m²) and lamberts (L), keep full floating-point precision (1 kcd/m² = 0.3141593 L; 1 L = 3.1830989 kcd/m²) during intermediate calculations and round only the final lambert figure to match your instrument tolerance.
