About this tool
Nox to Lux Converter
Convert nox to lux instantly. Free, bidirectional, and fully in-browser.
1 nox equals 0.001 lux — enter any nox value to convert it to lux instantly. This Nox to Lux converter is a client-side tool: it applies a single multiplication (lx = nox × 0.001) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert lux back to nox. A reference table lists common nox values already converted, and nothing you enter is sent to a server.

Why use Nox to Lux Converter
Instant, both ways
The result updates as you type, and the swap button flips the conversion to lux → nox without reloading.
Exact Illuminance math
The conversion uses the precise factor (lx = nox × 0.001), so the number matches a manual calculation to the decimal places you choose.
Adjustable precision
A slider sets 0–10 decimal places, and very small or very large results switch to scientific notation instead of rounding to zero.
Private and free
Everything runs locally in your browser — no upload, no account, no limit on conversions.
Common use cases
- Converting a nox measurement to lux for a spec, listing, or report.
- Checking nox↔lux figures while comparing products, datasets, or documentation.
- Learning the nox-to-lux relationship from the worked formula and the common-value table.
Frequently asked questions
How many lux are in a nox?
One nox is 0.001 lux. Multiply the nox value by 0.001 to convert. For example, 10 nox = 0.01 lx.
What is the formula to convert nox to lux?
lx = nox × 0.001. This tool applies it automatically and shows a worked example: 10 nox = 0.01 lx.
Can it convert lux back to nox?
Yes. Press the swap button, or type into the lux field, and the tool converts lux to nox using the inverse of the same relationship.
Is the conversion accurate?
It uses the standard illuminance definition (lx = nox × 0.001), not a rounded approximation, so results are exact to the number of decimal places you select.
Does this work offline and stay private?
Yes. The converter is a browser-side script with no network calls: your values are never uploaded, and once the page has loaded it keeps working without a connection.
