How to Convert Kilolux to Lux
To convert kilolux to lux, multiply the illumination by the following conversion ratio: 1,000 lux/kilolux.
Since one kilolux is equal to 1,000 lux, you can use this simple formula to convert:
The illumination in lux is equal to the illumination in kilolux multiplied by 1,000.
For example, here's how to convert 10 kilolux to lux using the formula above.
How Many Lux Are in a Kilolux?
There are 1,000 lux in a kilolux, which is why we use this value in the formula above.
Our kilolux to lux calculator automatically converts your illumination measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Kilolux and lux are both units used to measure illumination. Keep reading to learn more about each unit.
What Is a Kilolux?
A kilolux is a unit of illumination equal to 1,000 lux (lx), the base unit for illumination. Equal to 1,000 lux (outdoor daylight benchmark). [1]
The kilolux is classified as a metric and SI-compatible unit of illumination. Kilolux can be abbreviated as klx; for example, 1 kilolux can be written as 1 klx.
In the metric system, "kilo" is the standard SI prefix for thousands, or 10³. This makes the kilolux (klx) a convenient decimal multiple of the lux (lx).
In practice, kilolux (klx) are widely used across large-scale industrial, bulk, and macro-level illumination specifications within SI metric workflows, engineering documentation, and technical data sheets.
What Is a Lux?
SI derived unit of illuminance (1 lumen per square meter). It serves as a primary reference unit for measuring illumination across scientific and practical applications. [2]
The lux is classified as an International System of Units (SI) unit of illumination. Lux can be abbreviated as lx; for example, 1 lux can be written as 1 lx.
As the primary coherent reference unit for illumination in this category, all other illumination units are mathematically anchored to the lux (lx).
In practice, lux (lx) are widely used across standard illumination applications within International System of Units (SI) workflows, engineering documentation, and technical data sheets.
When converting illumination between kilolux (klx) and lux (lx), keep full floating-point precision (1 klx = 1,000 lx; 1 lx = 0.001 klx) during intermediate calculations and round only the final lux figure to match your instrument tolerance.
