Volume
1,539.3804cm³
- Capacity in litres
- 1.5394 L
- Volume in m³
- 0.001539 m³
1 litre = 1,000 cm³ and 1 m³ = 1,000 litres.

- V = πr²h
- V = π × 7² × 10 = 1,539.3804 cm³
How to use
- Choose the solid.
- Enter the measurements and choose a length unit.
- Read the volume and capacity; open "Show working" for the steps.
Good to know
Formulas: cube a³, cuboid l × b × h, cylinder πr²h, cone ⅓πr²h, sphere ⁴⁄₃πr³, hemisphere ⅔πr³, pyramid ⅓ × base area × h (rectangular base here) and prism base area × height. These come from the NCERT Class 8–10 "Surface Areas and Volumes" chapters.
Volume is shown in your unit cubed and converted to litres (1,000 cm³ = 1 litre, 1 m³ = 1,000 litres). This is useful for water tanks, buckets, cylinders and boxes.
For tanks, use the inside measurements: wall thickness reduces the real capacity. For the prism, enter the area of its cross-section (any shape) and its height or length.
Questions
How many litres are in 1 cubic metre?
1,000 litres. And 1 litre = 1,000 cm³.
How do I find the capacity of a cylindrical water tank?
Choose cylinder, enter the inner radius and height. The capacity in litres is shown below the volume.
Why is a cone one third of a cylinder?
A cone with the same base and height as a cylinder holds exactly one third of it, which is why V = ⅓πr²h.
What is the volume of a hemisphere?
Half of a sphere: ⅔πr³.
