How to Convert Lamberts to Candelas per Square Foot
To convert lamberts to candelas per square foot, multiply the luminance by the following conversion ratio: 295.7195613 candelas per square foot/lambert.
Since one lambert is equal to 295.7195613 candelas per square foot, you can use this simple formula to convert:
The luminance in candelas per square foot is equal to the luminance in lamberts multiplied by 295.7195613.
For example, here's how to convert 5 lamberts to candelas per square foot using the formula above.
How Many Candelas per Square Foot Are in a Lambert?
There are 295.7195613 candelas per square foot in a lambert, which is why we use this value in the formula above.
Our lambert to candela per square foot calculator automatically converts your luminance measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Lamberts and candelas per square foot 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 Candela per Square Foot?
A candela per square foot is a unit of luminance equal to 10.7639104 candelas per sq. meter (cd/m²), the base unit for luminance. Equal to 10.7639 cd/m². [2]
The candela per square foot is classified as a US customary unit of luminance. Candelas per Square Foot can be abbreviated as cd/ft²; for example, 1 candela per square foot can be written as 1 cd/ft².
When working with candelas per square foot (cd/ft²) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, candelas per square foot (cd/ft²) are widely used across standard luminance applications within US customary workflows, engineering documentation, and technical data sheets.
When converting luminance between lamberts (L) and candelas per square foot (cd/ft²), keep full floating-point precision (1 L = 295.7195613 cd/ft²; 1 cd/ft² = 0.0033816 L) during intermediate calculations and round only the final candela per square foot figure to match your instrument tolerance.
