About this tool
Lux to Nox Converter
Convert lux to nox instantly. Free, bidirectional, and fully in-browser.
1 lux equals 1000 nox — enter any lux value to convert it to nox instantly. This Lux to Nox converter is a client-side tool: it applies a single multiplication (nox = lx × 1000) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert nox back to lux. A reference table lists common lux values already converted, and nothing you enter is sent to a server.

Why use Lux to Nox Converter
Instant, both ways
The result updates as you type, and the swap button flips the conversion to nox → lux without reloading.
Exact Illuminance math
The conversion uses the precise factor (nox = lx × 1000), 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 lux measurement to nox for a spec, listing, or report.

- Learning the lux-to-nox relationship from the worked formula and the common-value table.
Frequently asked questions
How many nox are in a lux?
One lux is 1000 nox. Multiply the lux value by 1000 to convert. For example, 10 lx = 10000 nox.
What is the formula to convert lux to nox?
nox = lx × 1000. This tool applies it automatically and shows a worked example: 10 lx = 10000 nox.
Can it convert nox back to lux?
Yes. Press the swap button, or type into the nox field, and the tool converts nox to lux using the inverse of the same relationship.
Is the conversion accurate?
It uses the standard illuminance definition (nox = lx × 1000), 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.
