How Many Brass in One Truck? Measure Any Body in 2 Minutes

By Umer SattarUpdated 23 Oct 20263 min read

“Ek truck mein kitna brass aata hai?” is probably the most asked question at any sand depot. So how many brass in one truck? There is no single answer, because truck and trolley bodies come in many sizes and every load is filled differently. But anyone can find the real figure in two minutes with a measuring tape. This guide shows how, with worked examples, so the next bill can be checked on the spot.

How many brass in one truck: the two-minute method

  1. Ask for the load to be levelled while it is still on the truck. A heaped top hides missing volume.
  2. Measure inside the body: length and width at the floor, in feet.
  3. Measure the load height: from the floor of the body to the levelled top, in feet.
  4. Multiply and divide by 100: length × width × height ÷ 100 = brass.
Brass in the truck = Inside length × Inside width × Load height ÷ 100   (all in feet)

What if the body sides slope outwards?

Many tipper bodies are wider at the top. Measure the width at the floor and at the top of the load and use the average width.

Worked examples

Example bodies (measure your own: sizes vary)

Larger tractor trolley10 ft × 6 ft1.5 ft90 CFT0.9
Small tipper12 ft × 6.5 ft2.5 ft195 CFT1.95
Medium tipper14 ft × 7 ft2.5 ft245 CFT2.45
Large 10-wheel tipper18 ft × 7.5 ft3.25 ft≈ 439 CFT≈ 4.4

These are illustrations, not standards. Fabricators in every district build bodies to their own sizes, which is exactly why the tape measure matters more than any chart.

Volume vs weight: why a truck may not be “full”

A brass of damp river sand weighs about 4.5 tonnes; murum about 5 tonnes. A truck's legal payload limits the weight it may carry, so a body big enough for 5 brass may legally carry less when the material is heavy. Overloading is unsafe and is penalised under the motor vehicle rules, and the transporter's registration papers state the permissible weight.

Weight of common loads
LoadApprox. weight
2 brass river sand≈ 9 tonnes
3 brass gitti (20 mm)≈ 13.2 tonnes
4 brass murum≈ 20.4 tonnes

Checking the bill

  • Compare brass with brass: if the bill says 3 brass and the measured load is 2.45, the difference is real money.
  • Check the weighbridge slip if there is one: divide tonnes by about 4.53 for river sand to get brass.
  • Check the transit pass or royalty receipt for sand and murum; it records the quantity dispatched.
  • Note wet sand: soaked sand bulks up, so a brass of wet sand contains less actual sand.

Agree before dispatch whether the price is per brass, per tonne or per trip. “Per trip” is the riskiest for the buyer unless the body size and load height are agreed too.

Frequently asked questions

How many brass are in one truck?

It depends on the body. Measure inside length × width × levelled load height in feet and divide by 100. Small tippers often carry around 2 brass and large 10-wheel tippers around 4–5.

How many brass in a tractor trolley?

Usually under 1 brass, but measure it: length × width × load height in feet ÷ 100.

How do I convert truck tonnes to brass?

Divide the tonnes by about 4.53 for damp river sand, 4.39 for 20 mm gitti or 5.1 for murum.

Why does my truck hold less brass than its size suggests?

Legal weight limits cap the payload; heavy materials like murum can reach the limit before the body is full.

Should I pay per trip or per brass?

Per brass or per tonne is fairer; per trip only works if the body size and load height are agreed in advance.
