Foot-lamberts and kilocandelas per square meter are both units used to measure luminance. Keep reading to learn more about each unit.
What Is a Foot-lambert?
A foot-lambert is a unit of luminance equal to 3.4262591 candelas per sq. meter (cd/m²), the base unit for luminance. Cinema projection luminance unit (1/π cd/ft² ≈ 3.426 cd/m²). [1]
The foot-lambert is classified as a US customary unit of luminance. Foot-lamberts can be abbreviated as fL; for example, 1 foot-lambert can be written as 1 fL.
When working with foot-lamberts (fL) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, foot-lamberts (fL) are widely used across standard luminance applications within US customary 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 foot-lamberts (fL) and kilocandelas per square meter (kcd/m²), keep full floating-point precision (1 fL = 0.0034263 kcd/m²; 1 kcd/m² = 291.8635079 fL) during intermediate calculations and round only the final kilocandela per square meter figure to match your instrument tolerance.
