I did the Math like you did at first.
2100 lines in one inch
one inch = 25.4 mm
two inches = 50.8 mm
2.5 inches = 61.5 mm
1 cm = 2.54 inches
therefore 1 cm = 61.5 mm *****
1 mm = .0254"
!" = 39.37 mm
2" = 78.74 mm
2.5 " =97.42 mm

Further, your math is wrong. 2100/25.4 = 82 lines, which translates into 41 lp/mm. Keep in mind that these tests are at full contrast (i.e. Black lines on white background) so comparison to normal 50% MTF is difficult. Wondering what's for Dinner Tonight?
