Cylinder Volume Calculator in Millimeters (mm)

Maintained by the Editorial Team

Cylinder volume in millimetres uses the formula V = pi r squared h. For a precision pin with radius 20 mm and length 50 mm, multiplying pi times 400 times 50 gives 62,831.85 mm3, which equals 62.832 ml or 0.063 litres. Enter your millimetre dimensions below for high-precision volume calculations.

Millimeter volume equations and cc conversions

With radius and height in millimeters, volume is V = pi r squared h in mm3. Divide mm3 by 1,000,000 to get litres.

Frequently Asked Questions

How do I calculate volume using millimeters?

Multiply Pi by radius squared and height in millimeters: V = π × r² × h. The result is in cubic millimeters (mm³).

How do I convert mm³ to cm³?

Divide cubic millimeters by 1,000 to get cubic centimeters (cm³).

How do I convert mm³ to liters?

Divide cubic millimeters by 1,000,000 to get volume in litres.

What industries use millimeter volume?

Millimeter volume is used in CNC machining, 3D printing, precision engineering, optics, and medical device manufacturing.

Can I enter diameter instead of radius in mm?

Yes. Use our Diameter Calculator or divide your millimeter diameter by 2 to get the radius.
