1 diameter is equal to one meter because word dia is a constant, it comes from india so 1 diameter is equal to 1 meter
and one metre is equal to 100 cm and 1000 mm because 1 cm is equal to 10 mm

The confusion you are experiencing comes from the fact that this word has the word "meter" in it (and a severe lack of quality in the public education system but never mind that), but it is not an absolute amount.
1 diameter is the "width" of a circle. It is the longest straight line you can draw inside a circle before it touches 2 edges, and divides the circle into 2 equal halves.
A radius is the length between the centre of the circle, and the outside, the circumference. The diameter is = 2 * radius.
cm and mm are simply measurements of how much, you could have a 1cm diameter, a 1mm diameter, or a 500 gazillion bajillion (not real number) meter diameter.

The diameter is the distance across a circle. The units have to be defined by the math problem you're doing.
