How to Convert Lamberts to Kilocandelas per Square Meter
To convert lamberts to kilocandelas per square meter, multiply the luminance by the following conversion ratio: 3.1830989 kilocandelas per square meter/lambert.
Since one lambert is equal to 3.1830989 kilocandelas per square meter, you can use this simple formula to convert:
The luminance in kilocandelas per square meter is equal to the luminance in lamberts multiplied by 3.1830989.
For example, here's how to convert 5 lamberts to kilocandelas per square meter using the formula above.
How Many Kilocandelas per Square Meter Are in a Lambert?
There are 3.1830989 kilocandelas per square meter in a lambert, which is why we use this value in the formula above.
Our lambert to kilocandela per square meter calculator automatically converts your luminance measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Lamberts and kilocandelas per square meter are both units used to measure luminance. Keep reading to learn more about each unit.
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. [1]
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.
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). [2]
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.
When converting luminance between lamberts (L) and kilocandelas per square meter (kcd/m²), keep full floating-point precision (1 L = 3.1830989 kcd/m²; 1 kcd/m² = 0.3141593 L) during intermediate calculations and round only the final kilocandela per square meter figure to match your instrument tolerance.
