About this tool
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.
Open Lux to Nox Converter on AltFTool — it loads instantly in your browser.
Type the value you want to convert into the Lux field.
Read the equivalent in nox in the result field, and copy it if needed.
Use the decimal-places slider for more or less precision, or press swap to convert nox to lux.
The result updates as you type, and the swap button flips the conversion to nox → lux without reloading.
The conversion uses the precise factor (nox = lx × 1000), so the number matches a manual calculation to the decimal places you choose.
A slider sets 0–10 decimal places, and very small or very large results switch to scientific notation instead of rounding to zero.
Everything runs locally in your browser — no upload, no account, no limit on conversions.
One lux is 1000 nox. Multiply the lux value by 1000 to convert. For example, 10 lx = 10000 nox.
nox = lx × 1000. This tool applies it automatically and shows a worked example: 10 lx = 10000 nox.
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.
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.
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.
