How Much Does A 5 Gallon Bottle Of Water Weigh
If you’ve ever tried carrying a full 5-gallon jug to refill your water cooler, you know it’s not a light task. Many people wonder, how much does a 5 gallon bottle of water weigh?
Knowing the exact weight helps you lift it safely, plan for transportation, and understand how much water you’re really handling. Let’s break down the full details in the simplest way possible.

Understanding the Basics: How Water Weight Works
Water’s weight depends mainly on its density — that’s how tightly packed its molecules are.
At room temperature (around 70°F or 21°C), one gallon of water weighs 8.34 pounds (3.78 kilograms). When you multiply that by 5, you get:
5 gallons of water = 41.7 pounds (18.9 kilograms)
However, temperature and water purity can slightly change this number. Cold water is denser and a bit heavier, while warmer water is lighter. But the difference is very small — only a few grams.
So, whether it’s tap, purified, or spring water, the weight won’t change drastically.
How Much Does A 5 Gallon Bottle Of Water Weigh (Full Weight)
When you fill a standard 5-gallon bottle with water, it weighs roughly 41.7 pounds for the water alone. Add the bottle’s own weight (1.5 to 2 pounds), and the total weight becomes around 43–44 pounds (19.5–20 kg).
Here’s a simple table for better understanding:
| Type | Pounds | Kilograms |
|---|---|---|
| 1 Gallon of Water | 8.34 lb | 3.78 kg |
| 5 Gallons of Water | 41.7 lb | 18.9 kg |
| Empty Plastic Bottle | 1.5–2 lb | 0.7–0.9 kg |
| Full 5 Gallon Bottle | ≈43–44 lb | ≈19.5–20 kg |
That’s almost the same as a medium-sized dog or a carry-on suitcase full of clothes!

Factors That Affect the Weight of a 5 Gallon Water Bottle
Even though the difference is small, a few factors can slightly change the total weight of your 5-gallon jug.
1. Temperature
Colder water = denser = slightly heavier.
Warm water = expands a little = slightly lighter.
But the change is less than half a pound overall.
2. Type of Water
Distilled water: Lightest, as it has no minerals.
Spring water: Slightly heavier due to mineral content.
Purified/RO water: Average weight, very close to distilled.
3. Bottle Material
Plastic bottles are the lightest. Glass or stainless steel jugs can add several extra pounds to the total.
Empty vs Full 5 Gallon Bottle Weight
An empty plastic 5-gallon bottle weighs about 1.5–2 pounds (0.7–0.9 kg).
When filled with water, it jumps to 43–44 pounds (19.5–20 kg). That’s a huge difference, and it’s why you should always handle full bottles carefully.
If you use glass bottles, they can weigh up to 10–12 pounds empty, bringing the total close to 52–55 pounds when full.
Why Knowing the Weight Matters
You might be wondering — why do people even care how much a 5-gallon water jug weighs?
Here are a few practical reasons:
1. Safe Lifting
Lifting 40+ pounds incorrectly can hurt your back. Knowing the weight helps you use proper lifting techniques or assistive tools.
2. Storage and Transport
If you store several jugs for your office, camping, or emergencies, knowing the combined weight ensures your shelves, car, or truck can handle it.
For instance, 10 full bottles weigh 430–440 pounds total — about the same as two adults.
How to Safely Lift and Carry a 5 Gallon Water Bottle
Carrying a 5-gallon water jug safely is all about technique, not strength.
1. Lift With Your Legs
Bend your knees, keep your back straight, and lift slowly using your legs. Never bend at your waist — it strains your back.
2. Use a Dolly or Lifting Handle
Many people use a jug dolly or a bottle handle clip to move heavy bottles easily. It’s safer and helps avoid spills.
Conversions: 5 Gallon Bottle Weight in Pounds, Kilograms, and Liters
| Unit | Weight | Equivalent |
|---|---|---|
| 1 Gallon | 8.34 lb | 3.78 kg / 3.78 L |
| 5 Gallons | 41.7 lb | 18.9 kg / 18.9 L |
| Full Bottle (with container) | ~43–44 lb | ~19.5–20 kg |
This conversion is useful if you’re in a country that uses kilograms or liters instead of gallons and pounds.
Does Temperature Really Affect Water Weight?
Yes — but the difference is almost too small to matter.
As water warms up, it expands slightly, so the same 5 gallons weigh a bit less. The change is about 0.02 pounds per gallon per 10°F. That means a 5-gallon jug might vary by only 0.1 pound from cold to hot.
In daily life, it’s not noticeable.

Different Types of Water and Their Weights
| Type | Average Weight (lbs) | Notes |
|---|---|---|
| Distilled Water | 41.6 | Lightest due to lack of minerals |
| Purified (RO) Water | 41.7 | Common bottled water weight |
| Spring Water | 41.9 | Slightly heavier with minerals |
So while there are slight differences, the weight range stays around 41.6–42 pounds for the water alone.
What Does 5 Gallons of Water Feel Like?
Let’s make this relatable:
- It’s about as heavy as a 5-year-old child
- Feels like carrying two bowling balls
- Weighs about the same as a small suitcase packed for travel
No wonder it feels heavy when you lift it onto your water dispenser!
Practical Uses for Knowing Water Weight
- Camping: Helps plan how much water you can carry.
- Emergency Preparedness: Knowing total weight prevents overloading shelves.
- Fitness or DIY Workouts: Some people use full jugs for resistance training!
- Home Delivery Services: Easier to estimate delivery weight and storage space.
Storage and Handling Tips for 5 Gallon Water Bottles
- Store bottles upright in a cool, shaded place.
- Avoid direct sunlight — it can promote algae growth.
- Keep bottles sealed until you’re ready to use them.
- Check for cracks or leaks regularly.
- Rotate your stock to keep water fresh.
These habits ensure your bottled water stays safe and clean.
