As a rule of thumb, the density of water is 0.9998395 g/ml at 39.2°F (4°C), which means one US gallon of water weighs about 8.3454 pounds.
But if you don’t want to bother doing the calculations, this post is for you.
For your convenience, we at PowerSportsGuide have listed the weight of water in different quantities in one chart!
What is Water?
Water is a nearly colorless, odorless, and tasteless liquid at room temperature composed of oxygen and hydrogen. The chemical formula of water is H2O meaning that each water molecule consists of two hydrogens and one oxygen atom, which are connected by covalent bonds.
Although water seems to be colorless at the first glance (especially in small quantities), it has a slight blue color since it only absorbs the light at red wavelengths to a small extent.
Interestingly, water is the only substance on the Earth that naturally exists in all three states: solid, liquid, and gaseous.
It’s safe to say that water is one of the most essential substances on the planet. It can dissolve many other substances, which makes it indispensable for living organisms. Therefore, it’s no surprise that water is also essential for humans.
Water is transported in a wide variety of containers from tiny 32 oz. bottles to large industrial containers, so many want to know what’s the weight of water in different quantities.
Let’s drill into the details and talk about the weight of the water in detail!
What is the Standard Weight for Water?
Although the exact density of water is 0.9998395 g/ml at 39.2°F, it’s commonly rounded up to 1 g/m, which translates to 1 g/cm3, 1000 kg/m3, or 8.3454 lbs/US gal.
(Source: USGS.gov)
Based on that, the average weight of water in different commonly used containers is as follows (at 39.2°F):
- 8 oz. bottle of water: 0.522 lb.
- 12 oz. bottle of water: 0.782 lb.
- 16.9 oz. bottle of water: 1.06 lb.
- 32 oz. bottle of water: 2.09 lb.
- 75 oz. bottle of water: 4.89 lb.
- 1-liter bottle of water: 2.2 lb.
- 1-quart bottle of water: 2.086 lb.
- 1- gallon bottle of water: 8.35 lb
- 5-quart bottle of water: 10.43 lb.
- 5-liter bottle of water: 11.03 lb.
- 5-gallon bottle of water: 41.73 lb.
- 20-liter container of water: 44.1 lb.
- A 55-gallon drum of water: 459 lb.
- 330-gallon IBC tote of water: 2.754 lb.
