Because in any given measurement, there are more of the smaller units than bigger units.
There are less than 2 metres in my height (1.78 m). But in a smaller unit, eg centimetre, there are is 178 of them. That is a staggering 1780000 micrometres tall :) But, then again, that is only 0.00178 kilometres :(
Multiply
That depends on what you are converting from. If you are converting from larger units, you multiply. If you are converting from smaller units, you divide.
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.
When going from larger to smaller measurements, there will be more of them so it is necessary to multiply. 1 meter = 100 centimeters When going from smaller to larger measurements, there will be fewer of them so it is necessary to divide. 100 centimeters = 1 meter
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.
Multiply
Divide by the conversion factor to get the equivalent value in the smaller unit.
You convert to a larger unit. Smaller to larger. Metre is 1000 times larger than a millimetre
The answer to that one is going to depend on two things:-- what unit you are converting from-- what unit you are converting to
That depends on what you are converting from. If you are converting from larger units, you multiply. If you are converting from smaller units, you divide.
It could be either, depending on whether you're converting to a larger or smaller unit.
divide
No.
No, never.
False
False.
They aren't relevant units of measurement you boob.
