When you are converting from a unit to the next smaller unit where the difference is a factor of 10:
kilo - hecto,
hecto - deka
deka - unit
unit - deci
deci- centi
centi - milli
Other prefices involve steps of 1000.
You multiply by 1000.
Multiply by 5280.
Standard conversion factors are available and published and you use these to convert units from one to the other
Multiply by 10
Multiply by 10.
multiply the number by 12
You multiply by 1000.
Multiply by 5280.
Because the metric system is based on steps of 10 while the imperial system is completely random. For example: From milimeters to centimeters you multiply by 10. From meters to kilometers you multiply by 1000 ( *10 for decameters, *10 for hectometers, *10 for kilometers: 10*10*10=1000) From feet to yards you multiply by 3. From yards to miles you multiply by 1760. This makes convertering numbers in metric way easier than imperial... you just add or detract zeros.
Multiply by 1.00 . The same factor also produces greater units.
Multiply by (25 cc/unit)
Depends, what you want to convert to what. To convert between different metric units, powers of 10 are used. For example, a kilometer is 1000 meters. To convert from metric units to imperial units, you have to ask specific questions for specific units, for example, "how to convert inches to meters", or "how to convert pounds to kilograms".Depends, what you want to convert to what.

multiply by 10
Multiply square miles by 27,878,400 to get square feet.
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.

A millilitre is a unit of capacity. A centimetre is a unit of distance. The two units are therefore incompatible.
