Different units are often used to measure the same type of thing (for instance, length). Sometimes you want to convert to another unit, just to visualize the amount - for example, if you are accustomed to seeing lengths expressed in meters, you may have trouble understanding feet. Or perhaps the other way round. Also, when using formulae, units need to be compatible. As an example, in the formula commonly used for speed problems:
distance = speed x time
distance might be in meters, time in seconds, in which case speed must be in meters per second. If one of the units is incompatible, it must be converted first.

What conversion factor would you use to convert between these pairs of units?
To answer that accurately, we will need to know the pairs of units.
How long does it take to trale 15.6 miles in a car that is going 40 kmh?
In that case you need to divide the distance by the speed. Since the units are not compatible (miles versus km), you need to convert to compatible units first. For instance, convert the miles to kilometers.
How can I convert measurement of weight?
To convert a weight measurement, you need to know the conversion factor. For example, to convert pounds to kilograms, you multiply the number of pounds by 0.45. To convert kilograms to pounds, divide the number of kilograms by 0.45. Use the appropriate conversion factor depending on the units you are converting between.
