When verbally expressing metric units do people use decimal places?

Question

I am writing a script for an audio description, and am including an estimation of a statue that is 1.5 meters tall. For metric users, would this be expressed in speech as: "one point five meters" or "one and a half meters" If either works, then which is more intuitive?

Answer 1

One and one half meters.

Answer 2

Because metrics have a scale of 1000mm=40"; there's no need for fractions; unless you're referring to km.

1.5m sounds more professional.
