The two units answer different questions
Volume tells you how much room the pile takes. Weight tells you how hard the scale has to work. Brush, bagged household trash, and dense rubble can look similar in a truck and weigh nothing alike. A fee sheet may use either unit, or it may use both for different materials. Read the unit printed on the row you think applies. If a hauler quotes cubic yards and the site charges tons, you do not have a conversion that works for every material. Search Dumpmapper by ZIP code or city to see sites on a map. Listings can be out of date, so confirm with the site which unit is on its current fee sheet.
Do not borrow a conversion from the internet
Some industries publish typical weights for a material, and those figures are ranges with conditions. They are not your ticket. Moisture, soil stuck to debris, and how tightly the load is packed all move the weight. If you need a planning figure, ask the site whether they even use one, and ask the hauler which unit their quote uses. Then keep the quote in that unit until a scale measures the real load. Inventing a tonnage from a cubic-yard photo is how people argue with a ticket that was never wrong.
Say the unit out loud
When you call, repeat the unit you heard. Ask whether a minimum applies on top of that unit. Ask what happens with a mixed load that contains a light material and a heavy one. Write the row name beside the unit. At the scale, look at the ticket and check that the unit matches the conversation. If the ticket says tons and you planned in yards, ask the attendant to explain the row before you unload if you still can, or before you leave if you already did. The sheet is the authority. Your estimate was only a description.
Before you go
- Read the unit on the fee-sheet row that matches your material.
- Ask the hauler whether the quote is yards, tons, items, or time.
- Do not convert one unit into the other with a number you found online.
- Check the ticket's unit against the sheet before you leave.
Treating a cubic yard of rubble and a cubic yard of brush as the same bill.
Questions people ask
Which unit is cheaper?
Neither, by itself. The cheaper visit is the one whose posted row matches your material and whose total you calculated correctly. Ask the site to identify the row.
What if the sheet lists both?
Use the row the site says applies to your waste. Ask them to show you. Do not pick the unit that makes the napkin math look smaller.
