There are 8 pints in 1 gallon. This applies to both the US customary system and the imperial system, although the actual volume of a pint differs slightly between these systems. In the US customary system, 1 gallon equals 8 US pints, and 1 US pint is about 473 mL. In the imperial system, 1 gallon also equals 8 imperial pints, but 1 imperial pint is about 568 mL

. To summarize:

• 1 gallon = 8 pints (both US and imperial)
• 1 US pint ≈ 473 mL
• 1 imperial pint ≈ 568 mL

Therefore, when converting gallons to pints within the same measurement system, multiply the number of gallons by 8. For example, 2 gallons equal 16 pints
