| Jan 21, 2020 at 16:35 | comment | added | James Jenkins | @LorenPechtel, sure you could, it would just require more steps. Fill the pockets/compartments with bottles or bags of water (depending on the flexibility). When everything is full, measure the water used. | |
| Jan 21, 2020 at 15:54 | comment | added | Loren Pechtel | It depends on the pack. You couldn't measure mine this way because there are multiple compartments with some flexibility to the dividers between the compartments. | |

| Mar 30, 2018 at 22:55 | comment | added | Charlie Brumbaugh | @JamesJenkins Nobody is going hiking with an average density equal to water, 70 liters is 154 lbs which is more than a lot of outdoor people weigh | |

| Mar 30, 2018 at 11:06 | comment | added | James Jenkins | Related Why are backpacks sized in liters? @ShemSeger while it unlikely that a backpack will be filled with water, it is likely it will be filled with school books, tools or canned food; all of which are at least equivilent in density to water. It would be a poorly designed backpack that is not able to carry weight equal to it's volume of water without failing. | |
| Mar 29, 2018 at 17:06 | comment | added | ShemSeger | I could see someone's bag bursting at the seams being filled with 50-80kg. | |
| Mar 29, 2018 at 16:57 | comment | added | ShemSeger | @Erik With this being the accepted answer, I wholly expect you to post the measured volume of that backpack in mL, and share the link to the youtube video of the process ;) | |
| Mar 29, 2018 at 15:52 | comment | added | JPhi | To reiterate what @CharlieBrumbaugh pointed out, a 3000 cubic inch pack filed with water would weigh over 100 lbs. However, 3000ci seems like a very big pack - that's like 13 gallons/50 liters... | |

| Mar 28, 2018 at 20:19 | comment | added | berry120 | +1, but make sure it's not one of the bags that have small holes in the bottom..! | |
| Mar 28, 2018 at 20:01 | comment | added | Chris H | Rather than garbage bags I suggest rubble sacks; they're tougher and more likely to take the weight where they aren't well supported by the pack | |
| Mar 28, 2018 at 17:50 | comment | added | dwizum | Sand would work similarly to water. Or anything else fine and uncompressible. If you have a wood pellet stove, you could use pellet fuel. Lighter than sand or water, cheap enough that you won't be afraid of spilling or losing it. | |

minor typo

| Mar 28, 2018 at 17:32 | comment | added | Charlie Brumbaugh | This is probably the most precise method, however given how much water weighs, I foresee problems using this method with larger packs. | |
