How much does a gallon of water weigh? Simply put, one gallon of water weighs around 8.34 pounds (3.78 kg). Nevertheless, the actual weight of a gallon of water will depend on temperature, surface gravity, height, and pressure, as gallons measure volume rather than weight. From cooking to scientific research, several uses depend on knowing how much a gallon of water weighs. At room temperature (about 70°F or 21°C), a US gallon of water weighs around 8.34 pounds (3.78 kg); it is most dense at roughly 39.2°F (4°C) when it weighs roughly 8.345 pounds.
Summarizing the key information about how much a gallon of water weighs:
| Measurement | Weight |
|---|---|
| 1 gallon of water at 39.2°F (4°C) | 8.345 pounds (3.785 kg) |
| 1 gallon of water at room temperature (70°F or 21°C) | 8.33 pounds (3.78 kg) |
| 1 gallon of water (range based on temperature) | 8.288489 – 8.345404 pounds |
| 5 gallons of water at 39.2°F (4°C) | 41.72702 pounds (18.9 kg) |
| 5 gallons of water at room temperature (70°F or 21°C) | 41.64 pounds (18.9 kg) |
| 10 gallons of water at room temperature (70°F or 21°C) | 83.3 pounds (37.8 kg) |
| 1 cubic foot of water | 62.428 pounds (28.317 kg) |
| 1 liter of water | 2.205 pounds (1 kg) |
Key points:
- A gallon of water weighs around 8.34 pounds or 3.78 kg at room temperature
- The weight varies slightly based on temperature, with colder water being denser and heavier
- The weight of multiple gallons is simply the weight of one gallon multiplied by the number of gallons
- Other useful conversions include 1 cubic foot of water weighing 62.4 pounds and 1 liter weighing 2.2 pounds
Gravity, Pressure, and Height
Every object with mass experiences the force of gravity. Any item with mass will create a gravitational field, however, for extremely tiny objects, this field’s intensity is hardly noticeable. For huge objects like planets, nevertheless, gravity cannot be overlooked. Every day of our life we are affected by the gravitational field Earth creates. It affects the weight of items like water and keeps us linked to the surface of our planet. A thing that has more weight has a greater force of gravity. On Earth at sea level, for instance, a gallon of water weighs around 8.34 pounds; on Jupiter, the same gallon of water would weigh over 20 pounds.
Pressure has the same effect on item weight as gravity does. Though it is not the sole factor influencing pressure, gravity causes it. Additionally created by the atmosphere is pressure known as atmospheric pressure. greater pressure equals greater weight, the same as with gravity. Your height relative to sea level will also affect air pressure; so, the greater your altitude, the less atmospheric pressure you will encounter. As a result, at higher elevations, a gallon of water will weigh somewhat less.
Temperature
Temperature strongly influences water weight. At 39.2 degrees Fahrenheit (4 degrees Celsius), one gallon of water weighs around 8.34 pounds. As temperature affects the way water molecules are packed together inside a given volume, the actual weight of a gallon of water will vary. For instance, molecules will be packed closer together more tightly in colder water, therefore reducing the overall space taken within the water and raising the total density. Colder water will therefore be more weighty. Warmer water will have its molecules split apart, therefore increasing the water’s volume taken up and lowering the overall density. Warm water will weigh less, then.
