How Much Gas Is in a 9kg Bottle?
If you use LPG (Liquefied Petroleum Gas) for cooking, heating, or outdoor grilling, you might wonder: How much gas is in a 9kg bottle?
A 9kg gas bottle contains 8.5 to 9 kilograms of liquefied gas, which expands into a gaseous state when released for use. But how long will it last, and how do you measure the remaining gas? This guide explains everything you need to know.
How Much Gas Is in a Full 9kg LPG Cylinder?
A 9kg LPG bottle refers to the weight of the gas inside the cylinder—not the total weight of the cylinder itself. Here’s a quick breakdown:
- Full gas content: 9kg of LPG
- Empty cylinder weight: 8-10kg (varies by brand)
- Total weight when full: 17-19kg
💡 Tip: If you want to check whether your 9kg gas bottle is full, weigh it and subtract the cylinder’s tare (empty) weight.
How Long Does a 9kg Gas Bottle Last?
The lifespan of a 9kg gas bottle depends on how frequently you use it and the type of appliance. Here’s an estimate for common LPG uses:
| Appliance | Gas Consumption (MJ/h) | Approximate Duration (Hours) |
|---|---|---|
| Gas Braai (2-burner) | 15 MJ/h | 30 - 40 hours |
| Gas Heater (medium setting) | 30 MJ/h | 12 - 15 hours |
| Gas Stove (single burner) | 8 MJ/h | 100+ hours |
🛑 Important: The actual duration varies based on heat settings and appliance efficiency.
How to Check How Much Gas Is Left in a 9kg Bottle
There are several ways to check your LPG level before running out:
✅ 1. Weigh the Cylinder
- Look for the tare weight (TW) printed on the cylinder.
- Weigh your current bottle and subtract the tare weight.
✅ 2. Use Warm Water
- Pour warm water (not boiling) down the side of the cylinder.
- Wait a few seconds, then run your hand down the bottle.
- The point where it feels cool to the touch indicates the gas level.
✅ 3. Use a Gas Level Indicator
- Magnetic gas level indicators stick to the cylinder and change color to show the gas level.
