Watts to Candlepower Calculator

Watts to Candlepower Formula

The formula used to calculate candlepower (C) from watts (W) is:

\[ C = \frac{W \times PF}{12.57} \]

Where:

• \( C \) is the candlepower (candela)
• \( W \) is the wattage (watts)
• \( PF \) is the performance factor of the bulb (lumens per watt)

How to Calculate Candlepower from Watts?

To calculate candlepower, follow these steps:

1. Multiply the total wattage by the performance factor (lumens per watt).
2. Divide the result by 12.57 to obtain the candlepower in candelas.

What is Candlepower?

Definition:
Candlepower, also known as luminous intensity, is a measure of light intensity in a specific direction, typically measured in candelas (cd). It represents how much light is emitted in a particular direction and is often used in the context of lighting performance.
