Candle Power Solution

STEP 0: Pre-Calculation Summary
Formula Used
Candle Power = Luminous Flux/Solid Angle
CP = F/ω
This formula uses 3 Variables
Variables Used
Candle Power - (Measured in Candela) - Candle power is an older term used to describe the intensity of light emitted by a source, but it has largely been superseded by the SI unit candela for modern illumination measurements.
Luminous Flux - (Measured in Lumen) - Luminous flux is a measure of the total amount of light emitted by a light source in all directions. It quantifies the overall brightness or output of the source.
Solid Angle - (Measured in Steradian) - Solid angle is a measure of the extent of a cone-shaped region in three-dimensional space, originating from a point and defined by its vertex angle. It quantifies the spatial coverage.
STEP 1: Convert Input(s) to Base Unit
Luminous Flux: 42 Lumen --> 42 Lumen No Conversion Required
Solid Angle: 27 Steradian --> 27 Steradian No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
CP = F/ω --> 42/27
Evaluating ... ...
CP = 1.55555555555556
STEP 3: Convert Result to Output's Unit
1.55555555555556 Candela --> No Conversion Required

What is the realtion between candle power and lumens?

Candlepower, also known as candelas (cd), is a measure of luminous intensity. It quantifies the amount of light emitted by a light source in a specific direction. On the other hand, lumens (lm) measure the total amount of light emitted by a light source in all directions, regardless of the directionality.

To relate candlepower to lumens, you need to consider the beam angle or the angular distribution of the light emitted by the source. The total luminous flux in lumens can be calculated by multiplying the luminous intensity in candelas by the solid angle in steradians (sr) that the light is emitted within.

How to Calculate Candle Power?

Candle Power calculator uses Candle Power = Luminous Flux/Solid Angle to calculate the Candle Power, The Candle Power formula refers to a unit of measurement used to quantify the intensity of light emitted by a light source in a specific direction. Candlepower is an older term that has been largely replaced by the more standardized unit of measurement known as the candela (cd). The candela is defined as the luminous intensity in a given direction of a light source that emits monochromatic radiation at a frequency of 540 terahertz (THz) and has a radiant intensity of 1/683 watt per steradian. Candle Power is denoted by CP symbol.

How to calculate Candle Power using this online calculator? To use this online calculator for Candle Power, enter Luminous Flux (F) & Solid Angle (ω) and hit the calculate button. Here is how the Candle Power calculation can be explained with given input values -> 1.555556 = 42/27.

What is Candle Power?
The Candle Power formula refers to a unit of measurement used to quantify the intensity of light emitted by a light source in a specific direction. Candlepower is an older term that has been largely replaced by the more standardized unit of measurement known as the candela (cd). The candela is defined as the luminous intensity in a given direction of a light source that emits monochromatic radiation at a frequency of 540 terahertz (THz) and has a radiant intensity of 1/683 watt per steradian and is represented as CP = F/ω or Candle Power = Luminous Flux/Solid Angle. Luminous flux is a measure of the total amount of light emitted by a light source in all directions. It quantifies the overall brightness or output of the source & Solid angle is a measure of the extent of a cone-shaped region in three-dimensional space, originating from a point and defined by its vertex angle. It quantifies the spatial coverage.
