Calculate tank capacity, bitumen volume & weight
Enter tank dimensions + known weight or volume to find fill level percentage.
Bitumen Grade Density Reference

How to Use This Bitumen Tank Volume Calculator
This bitumen tank volume calculator works in three modes — cylindrical tanks, rectangular tanks, and fill-level reverse calculation. Follow these steps:
- Choose your tank shape using the tabs at the top: Cylindrical, Rectangular, or Fill Level.
- Enter tank dimensions — diameter and length for cylindrical tanks, or length × width × height for rectangular tanks.
- Set fill percentage — enter 100% if the tank is completely full, or a lower value for partial fill.
- Select bitumen grade — pick from common grades like VG-30 or VG-40, or enter a custom density value.
- Click “Calculate” — the tool instantly shows total capacity (m³ and litres), bitumen volume, and weight in kg and tonnes.
Use the Fill Level tab if you already know the current bitumen volume and want to find what percentage of the tank is filled.
How to Calculate Bitumen Tank Volume — Formula
The formula used depends on the tank shape.
Cylindrical Tank Formula
V = π × r² × L
Where:
- V = volume in cubic meters (m³)
- π = 3.14159
- r = radius (diameter ÷ 2) in meters
- L = length or height of tank in meters
To get bitumen volume at partial fill:
Bitumen Volume = V × (Fill% ÷ 100)
To get bitumen weight:
Weight (kg) = Volume (m³) × Density (kg/m³)
Rectangular Tank Formula
V = L × W × H
Where L = length, W = width, H = height — all in meters.
Bitumen Density Reference
| Grade | Penetration | Density |
|---|---|---|
| VG-10 | 60–70 Pen | ~1030 kg/m³ |
| VG-30 | 80–100 Pen | ~1040 kg/m³ |
| VG-40 | 40–50 Pen | ~1050 kg/m³ |
| PMB | Modified | ~1020 kg/m³ |
Note: Bitumen density varies slightly with temperature. Values above are standard reference densities at approximately 25°C.
Example
Scenario: A cylindrical bitumen storage tank has a diameter of 2.5 meters and a length of 6 meters. It is 80% full with VG-30 bitumen (density 1040 kg/m³). How much bitumen does it contain?
Step 1 — Total Tank Volume:
V = π × (2.5 ÷ 2)² × 6
V = 3.14159 × 1.5625 × 6
V = 29.45 m³ (full capacity)
Step 2 — Bitumen Volume at 80% Fill:
Bitumen Volume = 29.45 × 0.80
= 23.56 m³ (23,562 litres)
Step 3 — Bitumen Weight:
Weight = 23.56 × 1040
= 24,502 kg = 24.5 tonnes
This is a typical hot-mix asphalt plant tanker scenario. The bitumen tank volume calculator above handles this instantly.
Frequently Asked Questions
What is a bitumen tank volume calculator?
A bitumen tank volume calculator is a tool that computes the total storage capacity of a bitumen tank and how much bitumen volume and weight it currently holds, based on tank shape, dimensions, fill level, and bitumen grade density.
How do I calculate the volume of a cylindrical bitumen tank?
Use the formula V = π × r² × L, where r is the radius (half the diameter) and L is the tank length. Multiply the result by the fill percentage to get actual bitumen volume, then multiply by bitumen density (typically 1030–1050 kg/m³) to get weight in kg or tonnes.
What is the density of bitumen for volume calculations?
Bitumen density typically ranges from 1010 to 1060 kg/m³ depending on the grade. VG-10 (60–70 Pen) is approximately 1030 kg/m³, VG-30 (80–100 Pen) is ~1040 kg/m³, and VG-40 (40–50 Pen) is ~1050 kg/m³. Modified bitumen (PMB) is slightly lower at ~1020 kg/m³.
How do I convert bitumen volume from m³ to litres?
Multiply cubic meters by 1000. For example, 23.56 m³ × 1000 = 23,560 litres. The calculator above shows both units automatically in the results.
What is the difference between VG-30 and VG-40 bitumen for tank calculations?
The difference for volume calculations is in density — VG-40 (~1050 kg/m³) is slightly denser than VG-30 (~1040 kg/m³). For a 25 m³ tank, VG-40 would weigh about 250 kg more than VG-30 at full capacity. Always use the correct grade density for accurate weight calculations.
