Because the number of larger units will be less than the number of smaller
units, and when you divide the answer is usually smaller than the number
you started with.
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.
You divide the larger unit by a factor to convert into the smaller unit
you divide the smaller # into the bigger #----
Check one unit of the larger unit has how many units of the smaller unit (say has x units). Then divide the number of units you have of the smaller unit by x to get the answer
you divide or multiply
to get a unit
The metric system is based on the number 10. Every unit change, whether it be larger or smaller, is a multiple of 10. To change to a larger unit, simply multiply by 10. Do the reverse - divide by 10 - to change to a smaller unit. All metric units are changed like this.
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.
