You convert to a larger unit. Smaller to larger. Metre is 1000 times larger than a millimetre
It could be either, depending on whether you're converting to a larger or smaller unit.
Of course you multiply. As an example, the larger unit could be kilometer (that equal 1000 meter-the smaller unit); then 2 km (larger unit) = 2 x 1000 = 2000 meters (smaller unit)
The decimal point moves to the left.
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).
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.
Yes. For example, 100 grams = 0.1 kilograms
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.
