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.

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.
Decagram if going from larger unit to smaller unit, and decigram if from smaller to larger.

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.
You convert to a larger unit. Smaller to larger. Metre is 1000 times larger than a millimetre
A prefix can change the size of a unit when added to the front of it. For example, "kilo-" makes a unit larger and "milli-" makes a unit smaller.
To change a larger unit to a smaller unit, you would typically divide by the conversion factor. For example, to convert 1 meter to centimeters, you would multiply by 100 (as 1 meter is equal to 100 centimeters).

There are lots of small units in each big unit. As a result, the number of small units is greater and to go from a greater number to a smaller number you need to divide by a number which is biiger than 1.Alternatively, to change a smaller unit to a larger unit you can always multiply by a number which is between 0 and 1.
