How to Convert Candle to Lumen/steradian

Converting Candle (candle (German)) to Lumen/steradian (lm/sr) is a core calculation in Luminous Intensity, which measures the wavelength-weighted photometric power emitted by a light source in a direction per unit solid angle. Because Candle represents a larger magnitude than Lumen/steradian, converting from candle (German) to lm/sr expands the numerical figure. Exactly 1 Candle encompasses 1.05 Lumen/steradian. To convert any quantity, multiply the value in Candle by 1.05.

Mathematical Conversion Derivation via Coherent SI Base Unit

Under the International System of Quantities (ISQ), dimensional conversion between non-SI units is rigorously resolved by bridging through the coherent SI base unit (candela (cd)) without arbitrary rounding:

Vtarget=Vsource×(ksource→SIktarget→SI)V_{\text{target}} = V_{\text{source}} \times \left( \frac{k_{\text{source} \to \text{SI}}}{k_{\text{target} \to \text{SI}}} \right)
Universal Dimensional Conversion Law (ISO 80000 / NIST SP 811)
1. Source SI Bridge (ksource):1 candle (German) = 1.05 candela (cd)
2. Target SI Bridge (ktarget):1 lm/sr = 1 candela (cd)
Step-by-step substitution for Candle → Lumen/steradian:V(lm/sr) = V(candle (German)) × ( 1.05 / 1 ) = V(candle (German)) × 1.05
Mathematical FormulaValue in Lumen/steradian = Value in Candle × 1.05Direct computational formula applied for standard conversion.
Worked Example

For an engineering input of 36 candle (German), applying the conversion factor yields exactly 37.8 lm/sr. At larger operational scale, 5000 Candle corresponds to 5250 lm/sr.

Inverse check: 1 lm/sr = 0.952381 candle (German).

Frequently Asked Questions

There are exactly 1.05 lumens/steradian (lm/sr) in 1 candle (candle (German)). To calculate larger amounts manually, simply multiply your total number of candles by the conversion multiplier of 1.05.

The mathematical formula to convert candles to lumens/steradian is: [value] * 1.05 = lumens/steradian. Rather than doing the math manually, you can use our high-precision online calculator to process this exact equation instantly without rounding errors.

To perform the reverse calculation from lumens/steradian back to candles, you must divide your starting value by 1.05. Our bidirectional tool automatically computes this inverse equation the moment you type into the lumen/steradian input field.

1 Candle is larger than 1 Lumen/steradian. Specifically, 1 Candle equals exactly 1.05 lumens/steradian, making it 1.05 times larger (a difference of 0.02 orders of magnitude). Therefore, quantities expressed in lumens/steradian require a larger numerical value to represent the same physical amount.

Under standard international measurement guidelines, 1 Candle converts to 1.05 lumens/steradian. Precise numerical conversion factors ensure consistency across laboratory, engineering, and field data.
