Question

How many milliliters are equivalent to 2.7 liters?

Answer 1

`2700*mL`

Explanation:

The `"m"` prefix in `mL` means `"milli"`, i.e. `xx10^-3`.

And thus `(1*L)/(1*mL)=(1*cancelL)/(1*xx10^-3cancelL)=1/(10^-3)=1/(1/1000)=1000`, i.e. a `10^3` factor as required.

Note the arithmetic, `b/a^-1=b/(1/a)=axxb`, this is an important result for such dimensional analysis, as you can see in the given example.
