“The element vanadium is a solid at room temperature, and its density is 6110 kilograms per meter cubed. Its melting point is 1910 degrees Celsius.”

The statement gives claims that can be checked by observation or measurement: vanadium’s state at room temperature, density, and melting point. These are testable facts, so the statement is reliable on that basis. Using metric units or being brief does not by itself determine reliability.
