Tips for Converting Units of Measure Converting measures of units can sometimes be a nightmare; however, there are a few tips and tricks that can be used to convert one unit to another safely. For example, we can convert km/h (kilometers per hour) to m/s (meters per second) like this: One kilometer has 1000 meters and one hour has 3600 seconds, so the km/h is 1000/3600 = 0.277 m/s Tip 1 - In order to know how to make it 1000/3600 and not write it, 3600/1000 is doing the conversion as fractions. Tip 2 - Know when to divide and when to multiply. Aside from knowing how many km is equal to how many meters, the trickiest part of converting is knowing when you should be dividing the number or multiplying. For example, in our previous example, we understood that 1 km equals 1000 m but how to get the two units converted into the other. Here is how you do it: Remember, multiply gives us more, and division gives us less. Therefore, When we move from a bigger unit to the smaller one, we multiply When we move from a smaller unit to the bigger ones, we divide.
