Most 20 lb tanks have a tare weight of +/-

**17pounds**when completely empty. This means a "full" propane tankshould weigh about 37 pounds.

Similarly, it is asked, how much does a full 15 lb propane tank weigh?

Answer:The listed “TW” (Tare **Weight**) plus 17 pounds (4gallons of **propane**). So, two of mine will **weigh** 35pounds when **full** and the other two will **weigh** 33.6when **full**.

Size | Diameter | Weight |
---|---|---|

250 Gal | 30 | 500 |

500 Gal | 37 | 925 |

1000 Gal | 41 | 1775 |

Likewise, people ask, how much does a full 30 lb propane tank weigh?

55 lbs

This cylinder can safely hold slightly more than**100** lbs. Some cylinders can't quite hold 100lbs of**propane**. It depends on the actual volume of space leftinside the cylinder when it is manufactured. **Propane weighs**4.2 Lbs per **gallon** at 60°F, so 100.38 ÷ 4.2 =23.9 **gallons**.
