About this tool
Convert kilometers per hour to knots instantly. Free, bidirectional, and fully in-browser.
1 kilometer per hour equals 0.5399568035 knots — enter any kilometer per hour value to convert it to knots instantly. This Kilometer per hour to Knot converter is a client-side tool: it applies a single multiplication (kn = km/h × 0.5399568035) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert knots back to kilometers per hour. A reference table lists common kilometer per hour values already converted, and nothing you enter is sent to a server.
Open Kilometer per hour to Knot Converter on AltFTool — it loads instantly in your browser.
Type the value you want to convert into the Kilometer per hour field.
Read the equivalent in knots in the result field, and copy it if needed.
Use the decimal-places slider for more or less precision, or press swap to convert knots to kilometers per hour.
The result updates as you type, and the swap button flips the conversion to knot → kilometer per hour without reloading.
The conversion uses the precise factor (kn = km/h × 0.5399568035), 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 kilometer per hour is 0.5399568035 knots. Multiply the kilometer per hour value by 0.5399568035 to convert. For example, 10 km/h = 5.399568035 kn.
kn = km/h × 0.5399568035. This tool applies it automatically and shows a worked example: 10 km/h = 5.399568035 kn.
Yes. Press the swap button, or type into the knot field, and the tool converts knots to kilometers per hour using the inverse of the same relationship.
It uses the standard speed and velocity definition (kn = km/h × 0.5399568035), 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.
