c = 18u + 85 c - 85 = 18u (c - 85)/18 = u
10u softball is 35 ft. 12u to 18u is 40 ft. 18u gold and older is 43ft.
In 18 U Gold softball and collegiate softball, the distance from the plate to the pitching mound is 43 feet. This is because the pitchers at these levels throw much faster than the pitchers in the lower levels. In high school at 14U - 18U the pitching distance is 40 feet. Notice there is a difference between 18U and 18U Gold level.

Water molecules are composed from hydrogen and oxygen. Their atomic masses are 1 and 16 respectively. The molecular mass of water is 2x1+16=18u.
A water molecule has two hydrogen atoms attached to an oxygen atom. Their atomic masses are 1 and 16 respectively. So the molecular mass of water is 16+1x2=18u.
In USA hockey (I think in Canada, as well), there is Midget 16U (15 and 16) and Midget 18U (17 and 18). Players can play up an age level but cannot play down an age level.
