Convert Bitumen Tons to Liters
Last updated: 2026-10-03
How Many Liters in a Ton of Bitumen?
One metric ton of bitumen equals approximately 1,000 to 1,020 liters at a standard reference density of 1.01 kg/L (1.01 g/cm³). Using the industry-standard conversion factor, 1 ton of bitumen ≈ 1,000 liters, meaning 1 liter of bitumen weighs about 1 kg. The exact figure varies between 950 and 1,100 liters per ton depending on the bitumen grade, penetration value, and temperature at the time of measurement.
For fast calculations: liters = metric tons × 1,000 ÷ relative density. A 40-ton bitumen shipment at 1.01 density therefore measures roughly 39,604 liters — a number exporters, importers, and logistics teams need before booking tankers.
Bitumen Ton to Liters Conversion Table (By Grade)
Density is the only variable that changes ton-to-liter conversion between bitumen grades. The table below uses density figures measured at 25°C for common penetration and viscosity grades.
| Bitumen Grade | Density (kg/L at 25°C) | Liters per 1 Ton | Liters per 20 Tons | Liters per 40 Tons |
|---|---|---|---|---|
| Penetration 40/50 | 1.03 | 971 | 19,417 | 38,835 |
| Penetration 60/70 | 1.01 | 990 | 19,802 | 39,604 |
| Penetration 80/100 | 1.00 | 1,000 | 20,000 | 40,000 |
| Penetration 120/150 | 0.99 | 1,010 | 20,202 | 40,404 |
| VG-10 (viscosity grade) | 1.02 | 980 | 19,608 | 39,216 |
| VG-30 (viscosity grade) | 1.01 | 990 | 19,802 | 39,604 |
| VG-40 (viscosity grade) | 1.02 | 980 | 19,608 | 39,216 |
| Cutback bitumen (MC-30) | 0.92 | 1,087 | 21,739 | 43,478 |
| Bitumen emulsion (CSS-1h) | 1.01 | 990 | 19,802 | 39,604 |
| Oxidized/blown bitumen | 1.05 | 952 | 19,048 | 38,095 |
Key takeaway: the difference between the lightest and heaviest bitumen product is about 135 liters per ton — roughly 13%. On a 40-ton container, that spread equals more than 5,000 liters, which directly affects freight calculations, drum counts, and price-per-liter quotes.
Why Bitumen Density Changes by Grade (And Why It Matters for Pricing)
Density measures how tightly bitumen molecules pack together, and it is driven by three factors:
- Asphaltene content. Higher asphaltene grades (40/50, oxidized bitumen) are denser and yield fewer liters per ton — around 950–975 L.
- Temperature. Bitumen expands when heated. At 150°C (typical bulk shipping temperature), density drops to roughly 0.95 kg/L, pushing the conversion to about 1,050 liters per ton. Buyers who price by liter must specify the reference temperature.
- Product type. Cutback bitumen contains 20–40% solvent (kerosene or naphtha), which lowers density to 0.90–0.93 kg/L and raises liters per ton above 1,070. Emulsions contain 30–45% water and behave differently again.
Why this matters commercially: suppliers in many markets (especially Iran, Iraq, and the UAE) quote per metric ton, while buyers in drum-based markets often think in liters or gallons. A 0.02 swing in density changes a 40-ton load by nearly 800 liters. Without a locked density figure in the contract, both sides are exposed to disputes at discharge.
Ton vs Liter vs Barrel vs Drum: Bitumen Volume Comparison
Bitumen trades in several units simultaneously, so conversion fluency is essential. Here is how the units relate for a standard Penetration 60/70 grade at 1.01 kg/L:
| Unit | Equivalent Volume | Equivalent Weight | Note |
|---|---|---|---|
| 1 metric ton | 990 L | 1,000 kg | Standard trade unit |
| 1 liter | 0.00101 t | 1.01 kg | Retail/batch pricing unit |
| 1 US gallon | 0.00379 t | 3.79 kg | Used in US road projects |
| 1 barrel (158.99 L) | 0.1606 t | 160.6 kg | Rare — bitumen is not crude oil |
| 1 standard drum (200 L) | 0.202 t | 202 kg | 5 drums ≈ 1 ton |
| 1 IBC tote (1,000 L) | 1.01 t | 1,010 kg | Common for emulsion |
| 1 ISO tank (24,000 L) | 24.24 t | 24,240 kg | Bulk ocean freight |
| 1 bitumen tanker truck | 30,000–40,000 L | 30–40 t | Regional distribution |
Practical rule of thumb: 5 standard 200-liter drums hold almost exactly 1 ton of bitumen (5 × 200 = 1,000 L ≈ 1.01 t). This is why drum pricing and per-ton pricing converge so neatly in most markets.
Worked Example: Converting a 40-Ton Bitumen Order to Liters
Suppose you are importing 40 metric tons of Penetration 60/70 bitumen at a density of 1.01 kg/L, with a quoted price of $480 per ton (FOB Bandar Abbas).
Step 1 — Convert tons to liters:
- 40 t × 1,000 = 40,000 L
- 40,000 L ÷ 1.01 = 39,604 liters
Step 2 — Convert to drums:
- 39,604 ÷ 200 L = 199 drums (round to 200 for packing allowance)
Step 3 — Calculate price per liter:
- Total cost: 40 × $480 = $19,200
- Price per liter: $19,200 ÷ 39,604 = $0.485/L
Step 4 — Compare with a higher-density grade:
- At 1.03 density (40/50 grade): 38,835 L → $0.494/L
- Same tonnage, same ton price, but 769 fewer liters — a 1.9% higher cost per liter.
This is why experienced buyers always ask two questions: "What is the price per ton?" and "What is the certified density at 25°C?" The answers determine the true price per liter.
Common Conversion Mistakes in Bitumen Trading
- Using water density (1.0) for all grades. Accurate for Pen 80/100, but wrong by up to 5% for oxidized bitumen and 8–10% for cutback.
- Measuring density at the wrong temperature. A density certified at 15°C versus 25°C differs by roughly 0.01–0.012 kg/L.
- Confusing metric tons with short tons. 1 short ton = 907 kg = approximately 898 liters of Pen 60/70 — a 10% error if mixed up.
- Assuming 1 ton = exactly 1,000 liters in contracts. Safest approach: state the assumed density in the sales agreement.
- Ignoring expansion during heated transport. Bulk bitumen shipped at 150–170°C occupies more volume at loading than at discharge. Custody-transfer figures must state temperature.
Verification checklist before signing:
- Density and reference temperature stated in the contract
- Conversion factor agreed in writing (e.g., 1 t = 990 L at 25°C)
- Independent lab certificate (ASTM D70 or D1298) on file
- Tolerance clause for ±0.5% measurement variance
FAQ: Bitumen Ton to Liters Conversion
How many liters are in 1 ton of bitumen?
One metric ton of bitumen equals approximately 990 to 1,010 liters for standard penetration grades at 25°C, based on densities of 0.99–1.01 kg/L. For quick estimates, use 1 ton = 1,000 liters, then adjust by the grade's certified density.
How many liters is 1 ton of bitumen 60/70?
Penetration 60/70 bitumen has a density of about 1.01 kg/L, so 1 ton equals 990 liters. A 20-ton shipment equals 19,802 liters, and a 40-ton shipment equals 39,604 liters.
Does 1 liter of bitumen equal 1 kg?
Almost — 1 liter of standard bitumen weighs 0.99 to 1.03 kg depending on grade and temperature. Only Pen 80/100 hits exactly 1.00 kg/L at 25°C. Denser grades like oxidized bitumen weigh up to 1.05 kg per liter.
How many drums of bitumen are in 1 ton?
A standard bitumen drum holds 200 liters, so 1 ton of Pen 60/70 (990 L) fills approximately 5 drums. Exporters typically ship 40-ton lots as 200 drums, allowing a small packing tolerance.
What is the formula to convert tons to liters for bitumen?
Use: Liters = Metric Tons × 1,000 ÷ Density (kg/L). For 25 tons of VG-30 at 1.01 kg/L: 25,000 ÷ 1.01 = 24,752 liters. Always use the density from the batch certificate, not a generic value.
