Convert Between Units of Pressure
Speed measures how fast something moves. It is used in transportation, fluid flow velocity, wind engineering, and machinery. Common units include meters per second (m/s), kilometers per hour (km/h), miles per hour (mph), feet per second (ft/s), and knots. Converting speed units is useful when comparing standards and datasets that use different conventions.

About Pressure Conversions
Helpful context and notes for converting Pressure units.
A useful anchor is that 1 m/s equals 3.6 km/h. That makes quick checks easy: 20 m/s is 72 km/h, and 30 m/s is 108 km/h. Speed is sometimes used in squared relationships, such as wind pressure and dynamic effects, so a unit mistake can be amplified. Also note that some sources report peak values while others report averages (for example, gust wind speed vs sustained wind speed).
Practical tip: convert and then sanity-check magnitude. A design wind speed of 120 km/h should be about 33.3 m/s. If you accidentally treat km/h as m/s, the implied speed is 3.6 times higher, and any squared load relationship will be about 13 times higher. For marine and aviation contexts, confirm whether the source uses knots. If a speed value drives loads or safety decisions, keep the original unit noted alongside the converted value.

Fun Fact
One knot is one nautical mile per hour. At take-off, a 747 is hurtling down the runway at around 170 knots - also known as 'too late to change your mind' speed.
