About this tool
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.
Open Nox to Lux Converter on AltFTool — it loads instantly in your browser.
Type the value you want to convert into the Nox field.
Read the equivalent in lux in the result field, and copy it if needed.
Use the decimal-places slider for more or less precision, or press swap to convert lux to nox.
The result updates as you type, and the swap button flips the conversion to lux → nox without reloading.
The conversion uses the precise factor (lx = nox × 0.001), 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 nox is 0.001 lux. Multiply the nox value by 0.001 to convert. For example, 10 nox = 0.01 lx.
lx = nox × 0.001. This tool applies it automatically and shows a worked example: 10 nox = 0.01 lx.
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.
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.
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.
