how do i convert km/hr to m/s?

The basic formula for converting kilometers per hour (km/hr) to meters per second (m/s) is: m/s = km/hr × 1000/3600. This formula comes from the fact that there are 1000 meters in a kilometer and 3600 seconds in an hour.
We multiply by 1000/3600 in the conversion process because there are 1000 meters in a kilometer (hence the multiplication by 1000) and 3600 seconds in an hour (thus dividing by 3600). This conversion factor adjusts the speed from a larger unit (km/hr) to a smaller unit (m/s).
Sure! Let's convert 90 km/hr to m/s. Using the formula: m/s = km/hr × 1000/3600, we calculate 90 × 1000/3600 = 25. Therefore, 90 km/hr is equal to 25 m/s.
A simple way to remember is to think of the conversion factor as dividing by 3.6. Since 1000/3600 simplifies to approximately 1/3.6, you can quickly convert km/hr to m/s by dividing the speed in km/hr by 3.6.
The conversion from km/hr to m/s is mathematically accurate and precise. As it's a direct unit conversion, the accuracy is as good as the accuracy of the initial speed measurement in km/hr.
