1 M is a larger concentration than 1 mM. As I M = 10^3 mM.
Similar to how 1 meter is greater than 1 millimeter, as a meter is 1000 millimeters. Anytime you write something as 1 unit = 10^(positive integer) (more specifically some number greater than 1) units. The unit on the left hand side is greater, when looking at a 1 to 1 comparison.
