I would use a micrometer. A caliper would do as well.
If I was you i would use millimetres or centimetres.

If you were to calculate the mass of a nickel you would use grams or milligrams if you were to measure the diameter of a nickel you would use millimeters.
Millimeters.

That depends what aspect of a marble you want to measure, for example its diameter, its mass, its density, its color, etc.

First of all it's "What unit of measurement would you use to measure the diameter of a drink can?" Secondly you would probably use either centimeters or inches, depending on where you are in the world.
use an ometer
centimeters or millimeters
To determine the size of a single marble, you can measure its diameter using a caliper or ruler. If the marble is spherical, you can also calculate its volume by measuring its diameter, applying the formula for the volume of a sphere (V = 4/3 × π × r³, where r is the radius). Additionally, you can weigh the marble and use its density to find its volume, which can then be related back to its size.
