How many ml in one ruler?

Answer 1

That depend on how long the ruler is.

The 2 rulers in my desk drawer have 200 and 300 milimeters markings respectively. I also have a triangle with 195 millimeter markings on one side. I just looked in another drawer and found a ruler with 400 mm markinga and a folding carpenter's rule with 2000 markings.

Answer 2

There are 25.4 millimeters to an inch, so there are 304.8 millimeters in a twelve inch ruler.

Answer 3

AS ml are a VOLUME measure, it is impossible to have them on a ruler.
