Converting km/hr to m/s: What is the formula?

In summary, to convert km/hr to m/s, you can follow these steps: first, multiply the km/hr value by 1000 to convert it to m/s. Then, divide the value by 3600 to convert from hours to seconds. Alternatively, you can simply divide the km/hr value by 3.6 to get the equivalent m/s value. This method is easy to use in all situations and can even be used for conversions involving minutes or other units.

If you want to save time...
m/s - km/h *3.6
km/h - m/s /3.6

You want a method of converting that is easy to use in all situations. The one I like goes like this:

100 km/h = 100 * 1000 m/3600 s = ...
You just replace the km with 1000m, and the hour with 3600 s.
This method always works and soon you don't even have to think about it. You can even do km/hr/minute or something weird like that.

km/hr to m/s Formula: divide the speed value by 3.6
 

What is the basic formula to 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.

Why do we multiply by 1000/3600 in the conversion?

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).

Can you provide a step-by-step example of converting km/hr to 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.

Is there an easy way to remember this conversion?

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.

How accurate is the conversion from km/hr to m/s?

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.
