A US gallon = 3.785 litres. Gallon water bottles are popular with fitness and bodybuilding communities for high daily hydration targets. In India, gallon bottles are typically plastic (BPA-free Tritan, ₹500–1500) — heavier steel gallons are rare. For daily use, gallon bottles are heavy and cumbersome; most Indian users pick 1L–2L instead. If you need gallon capacity, look for BPA-free Tritan plastic with a wide-mouth lid; certified insulated steel is rare at this size and very expensive.
