Question #4fdc7

Answer 1

You convert gallons to litres and then to millilitres.

I will use Imperial gallons. (The conversion factor for US gallons is 1 US gal = 3.785 L).

EXAMPLE:

Convert 10.0 gallons to millilitres.

10.0 gal × `(4.546 L)/(1 gal)` = 45.5 L

45.5 L × `(1000 mL)/(1 L)` = 45 500 mL = 4.55 × 10⁴ mL

Notice how we set up the conversion factors to make the units cancel.
