Cylinder Volume in Milliliters

Calculate the volume of any cylinder in milliliters. Since 1 milliliter equals exactly 1 cubic centimeter, just measure in centimeters and apply V = πr²h — the number you get is already in mL. This tool does it automatically.

V = πr²h (cm³ = mL)
1 cm³ = 1 mL cm³ ≡ mL

Milliliters and Cubic Centimeters

1 cm³ ≡ 1 mL (exact)

One milliliter (mL) equals one cubic centimeter (cm³) exactly. This makes conversion simple: if you calculate cylinder volume in cm³, the number is the same in mL.

This relationship exists because the milliliter was defined as the volume of 1 cm³ of water. So a cylinder with r = 2 cm and h = 5 cm has V = π × 4 × 5 = 62.83 cm³ = 62.83 mL.

Small Cylinders in Milliliters

Milliliters are ideal for small cylindrical objects. A test tube (r = 0.75 cm, h = 10 cm) holds about 17.67 mL. A shot glass shaped as a cylinder (r = 2 cm, h = 5 cm) holds about 62.83 mL. A standard syringe barrel (r = 0.5 cm, h = 6 cm) holds about 4.71 mL.

In medicine, cooking, and chemistry, milliliters are the go-to unit for liquid volumes under 1 litre. For volumes above 1,000 mL, switch to litres for cleaner numbers.

Converting Other Units to Milliliters

cm³ → mL → L mL ↔ L ↔ oz ↔ cups

From cubic inches: multiply by 16.387 to get mL. From fluid ounces (US): multiply by 29.5735. From teaspoons: multiply by 4.929. From tablespoons: multiply by 14.787.

If you measured your cylinder in inches, first calculate volume in cubic inches, then multiply by 16.387. For a cylinder with r = 1 in, h = 3 in: V = π × 1 × 3 = 9.42 in³ = 154.4 mL.

Frequently Asked Questions

How many mL in a cylinder with 3 cm radius and 10 cm height?
V = π × 9 × 10 = 282.74 cm³ = 282.74 mL.
Is 1 mL the same as 1 cc?
Yes. 1 mL = 1 cm³ = 1 cc. These three units are identical in volume.
How do I convert mL to fluid ounces?
Divide mL by 29.5735 for US fluid ounces. For example, 250 mL = 8.45 US fl oz.
How many mL does a standard drinking glass hold?
A typical cylindrical glass (r ≈ 3.5 cm, h ≈ 12 cm) holds about π × 12.25 × 12 = 461.8 mL, roughly 462 mL.
How do I measure small cylinder volumes accurately?
For small cylinders, use a graduated cylinder or syringe. Fill the cylinder with water, pour it into the graduated cylinder, and read the meniscus at eye level for the mL measurement.
