Similarly, in chemical engineering, precise conversions are needed for scaling up chemical reactions from the laboratory to industrial production. The conversion factor of 3.78541 liters per US gallon must be applied accurately to avoid significant errors.

Other Volume Units It's also helpful to understand how liters and gallons relate to other common units of volume. In the metric system, the liter is related to other units by powers of ten:

• 1 milliliter (mL) = 0.001 liters
• 1 kiloliter (kL) = 1000 liters In the US customary system, the gallon is related to other units as follows:
• 1 fluid ounce (fl oz) = 1/128 gallons
• 1 pint (pt) = 1/8 gallons
• 1 quart (qt) = 1/4 gallons

Understanding these relationships can help in performing more complex conversions and calculations.
