There isn't any one general answer. It depends on what unit you want to convert to what other unit.
The metric system is used by scientists because it is based on factors of ten. This makes it easy to convert from one unit of measurement to another.
You can't convert that. In general, you can only convert from one unit to another of the same kind, for example, one unit of mass to another unit of mass.
You can't convert that. You can convert from one linear unit to another linear unit, or from one square unit to another square unit, but not between linear units and square units.
A multiplier.
There isn't any one general answer. It depends on what unit you want to convert to what other unit.
To convert from one metric unit to another, use conversion factors. Multiply the value you are converting by the appropriate conversion factor to get the desired unit. For example, to convert meters to centimeters, multiply by 100 since there are 100 centimeters in one meter.
Metric unit is easy. Costomary unit is an advanced unit
move the decimal point the the correct spot
The conversion factor for changing one unit of length to another in the metric system is a multiple of 10, as the metric system is based on the power of 10. This means that to convert from one unit of length to another, you simply need to multiply or divide by 10 or its multiples such as 100, 1000, etc.
You don't really "convert a unit of measurement"; you convert from one unit to another. The two - "from" and "to" are always required.
That means that if you have a measurement in one unit, you convert it to another unit. For example, if a measurement is given in millimeters, you may need to convert it to meters.

You can't convert that. You can convert from one unit of length to another, or from one unit of area to another, but you can't convert between units of length and area.
