Converting knots to meters per second
To convert knots to meters per second, multiply the value by 0.51444444. Speed conversions appear in wind loading, air velocity in ducts and transport analysis, where codes mix metric and imperial units.
Meters Per Second (m/s)
Meters per second (m/s) is the SI derived unit of speed.
- Origin
- Defined directly from the SI meter and second.
- Where it is used
- Used for wind speed in structural codes, air velocity in ducts and lift travel speed.
- Relation to SI
- The SI reference unit for speed in this converter.
Frequently asked questions
How many meters per second are in one knot?
1 kn equals 0.51444444 m/s.
How do I convert knots to meters per second?
Multiply the value by 0.51444444. For example, 10 kn equals 5.1444444 m/s.
How do I convert back from meters per second to knots?
1 m/s equals 1.9438445 kn. The converter above works in both directions, so you can type into either field.
Which speed unit do wind load codes use?
Eurocode and most metric standards state basic wind speed in meters per second, while US standards such as ASCE 7 use miles per hour. Check the averaging period as well as the unit.
What is a knot?
