How to Convert Nox to Kilolux
To convert nox to kilolux, multiply the illumination by the following conversion ratio: 0.000001 kilolux/nox.
Since one nox is equal to 0.000001 kilolux, you can use this simple formula to convert:
The illumination in kilolux is equal to the illumination in nox multiplied by 0.000001.
For example, here's how to convert 5 nox to kilolux using the formula above.
How Many Kilolux Are in a Nox?
There are 0.000001 kilolux in a nox, which is why we use this value in the formula above.
Our nox to kilolux calculator automatically converts your illumination measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Nox and kilolux are both units used to measure illumination. Keep reading to learn more about each unit.
What Is a Nox?
A nox is a unit of illumination equal to 1/1,000 of a lux (0.001 lx). Dark-adapted illuminance unit equal to 1 millilux (0.001 lx). [1]
The nox is classified as a metric and SI-compatible unit of illumination. Nox can be abbreviated as nx; for example, 1 nox can be written as 1 nx.
When working with nox (nx) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, nox (nx) are widely used across fine-tolerance laboratory, analytical, and micro-scale illumination measurements within SI metric workflows, engineering documentation, and technical data sheets.
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). [2]
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.
When converting illumination between nox (nx) and kilolux (klx), keep full floating-point precision (1 nx = 0.000001 klx; 1 klx = 1,000,000 nx) during intermediate calculations and round only the final kilolux figure to match your instrument tolerance.
