Multiply
To convert from a larger unit to a smaller unit you would multiply. Ex: 5 km = 5000 m Where 1 km = 1000 m <><><><><> It depends on which factor you are multiplying or dividing by. It can go either way. To convert from ounces to grams, for instance, you can divide by 28.350, or you can multiply by 0.035273.
It makes sense to multiply when converting measurements to smaller units because it takes many smaller units to make up a larger unit. So in order to translate larger unit(s) into smaller units, you have to break up the larger unit(s) into many smaller pieces.
There are two ways that are essentially the same and can be used freely - as long as the two units are of the same dimension (length, mass, time, etc.) of course.First way: MultiplicationYou multiply with the relation between the largerunit and the smaller unit, i.e. with how many of the larger unit that goes per one of the smallerunit.ExamplesIf the smaller unit is m (meter) and the larger is km (kilometer), you multiply by 1/1000 km/m.If the smaller unit is inches (in) and the larger is feet (ft), you multiply by 1/12 ft/in.If the smaller unit is µg (micrograms) and the larger is kg (kilograms), you multiply by 1/1,000,000,000 kg/µg.Second way: DivisionYou divide by the relation between the smallerunit and the larger unit, i.e. with how many of the smaller unit goes per one of the larger unit.ExamplesIf the smaller unit is m (meter) and the larger is km (kilometer), you divide by 1000 m/km to go from meters to kilometers.If the smaller unit is inches (in) and the larger is feet (ft), you divide by 12 in/ft to go from inches to feet.If the smaller unit is µg (micrograms) and the larger is kg (kilograms), you divide by 1,000,000,000µg/kg.
When converting from a larger unit to a smaller unit there will be more of them, so multiply by the conversion factor; eg km to m: there a 1000m in 1 km, so multiply by 1000 so 2.4 km = 2.4 x 1000 m = 2400 m When converting from a smaller unit to a larger unit there will be less of them so divide by the conversion factor; eg m to km: there are 1000m in 1 km so divide by 1000, so 2400 m = 2400 ÷ 1000 km = 2.4 km

because you have to multiply to break it down into a smaller number
False - when converting from a larger unit to a smaller unit there will be more of them so you must multiply. What you multiply by depends upon the units, for example converting feet to inches you multiply by 12; converting pounds to ounces you multiply by 16. It is only with the metric system of units where you multiply by a power of 10 to convert a large unit to a smaller unit, for example 2.5 kg is 2500 g (multiply by 1000 or 103).

Example. (meters to millimeters) There are more millimeters in a metre(1000 to be precise) Therefore you multiply by 1000 to get from metres to millimeters That is wrong we don't want an example You have multiply because the larger unit has to broken down into plenty of smaller measurements or units. When you do that the number is multiplied into many smaller units.
To convert a given unit to a larger unit, you need to determine the conversion factor between the two units. Divide the given value by the conversion factor to get the answer in the larger unit.
When changing from a larger unit to a smaller unit, there will be more of them, so you will multiply.
