Sand is heavy af. A ton is only like 20 cubic feet. Still… that’s not very much money.

- lostlogin 2y agoMy eye is twitching remembering a fiasco where someone ordered concrete assuming 1 cubic metre required 1 ton of concrete. Ever since that I’ve assumed it’s about 2.5 tons per cubic metre. This works much better.
- blackguardx 2y agoBut concrete is measured by volume at least in the US (cubic yards…sigh). I think this is because different mix designs can change the resulting weight. I’ve even heard of adding air to make for better pumping.
