# Footcandles to lux calculator

Easily convert illuminance from footcandles (fc) to lux (lx) with this user-friendly online tool. Perfect for lighting professionals, architects, and engineers working on international projects. Obtain accurate lux measurements by converting footcandles using this convenient calculator.

## What is Footcandles to lux

Footcandles (fc) and lux (lx) are both units of measurement used to describe illuminance, which is the amount of light that falls on a surface. The main difference between them is the system of units they belong to. Footcandles are commonly used in the United States, while lux is the internationally recognized unit.

To convert footcandles to lux, you can use the following conversion factor:

1 footcandle = 10.764 lux

Therefore, to convert from footcandles to lux, you would multiply the value in footcandles by 10.764. Conversely, to convert from lux to footcandles, you would divide the value in lux by 10.764.

For example, if you have a measurement of 100 footcandles, you can convert it to lux by multiplying 100 by 10.764, resulting in 1076.4 lux.

It's important to note that this conversion assumes a standard relationship between the two units and does not take into account any variations due to the spectral distribution of the light source or other factors.

## Lux to footcandles conversion formula

The illuminance *E*_{v} in lux (lx) is equal to the illuminance *E*_{v} in footcandles (fc) divided by 0.09290304:

*E*_{v(lx)} =
*E*_{v(fc)}* */ 0.09290304 =
*E*_{v(fc)}* *× 10.76391

## Footcandles to lux Example

Assuming you have a light source with different illuminance values in Footcandles (fc) and you want to convert them to Lux (lx), you can use the following table:

Illuminance (fc) | Conversion Factor | Illuminance (lx) |
---|---|---|

100 | 10.764 | 1076.4 |

50 | 10.764 | 538.2 |

20 | 10.764 | 215.3 |

10 | 10.764 | 107.6 |

To convert Footcandles to Lux, you need to multiply the illuminance in Footcandles by the conversion factor, which is approximately 10.764.

For example, if the illuminance is 100 fc, the corresponding illuminance in Lux would be 100 fc * 10.764 = 1076.4 lx.

Similarly, for an illuminance of 50 fc, the illuminance in Lux would be 50 fc * 10.764 = 538.2 lx.

You can follow the same calculation for other values in the table.

Please note that this conversion assumes idealized conditions and a uniform distribution of light. In practical scenarios, the actual illuminance may vary depending on the specific characteristics of the light source and the lighting environment.
