model measuring

Ok so me and my bro are making this snowboarding game and everything was going ok intill I decided
to make everything the right scale but I can’t seem to figure out how to measure anything.
Is the grid in the backgrounded in square meters or what? Anyway though any tips and tricks would be much appreciated.

At the highest level of magnification, the grid squares are 1 unit wide which, long story short, is equivalent to 1 metre in Unity. A handy trick to get an impression of scale is to create a cube or sphere near to your object for comparison.

Thanks andeeee
