Converting liters to milliliters uses the fact that 1 liter equals 1000 milliliters. To turn liters into milliliters, multiply by 1000. So 3 liters is 3 × 1000 = 3000 milliliters. The other options represent different quantities: for example, 3 mL is much less than a liter (0.003 L), 0.003 mL is even smaller, and 300 mL is 0.3 L, not 3 L.
