Cylinder Volume in Litres
Need your cylinder volume in litres? Enter the radius and height in centimeters, and this calculator gives you the result in litres instantly. One litre equals 1,000 cubic centimeters — so the tool divides πr²h by 1,000 for you.

How to Convert Cylinder Volume to Litres
Start with the standard cylinder formula: V = π × r² × h. If your measurements are in centimeters, the result is in cubic centimeters (cm³). Since 1 litre = 1,000 cm³, divide by 1,000.
Example: A cylinder with radius 10 cm and height 30 cm has V = π × 100 × 30 = 9,424.78 cm³. That's 9.42 litres.
If your measurements are in meters, multiply cubic meters by 1,000 to get litres. If in inches, first convert to cm (1 inch = 2.54 cm), then follow the same steps.
Common Cylinder Sizes in Litres
A standard soda can (r = 3.3 cm, h = 12.2 cm) holds about 0.33 litres. A typical water bottle (r = 3.5 cm, h = 20 cm) holds about 0.77 litres. A 20-litre jerry can is roughly cylindrical with r = 14 cm and h = 32.5 cm.
Knowing these benchmarks helps you estimate without a calculator. A cylinder about the size of your forearm holds roughly 1–2 litres. A large bucket (r = 15 cm, h = 30 cm) holds about 21 litres.
When to Use Litres for Cylinder Volume
Litres are the most practical unit for liquids and gases in everyday life. Use litres when filling tanks, measuring fuel, cooking, or sizing aquariums. Most countries outside the US use litres as the standard volume unit.
For very small cylinders (like syringes), millilitres work better. For very large cylinders (like industrial tanks), cubic meters or kilolitres are more convenient. But for household and mid-size applications, litres strike the right balance between precision and readability.
