N51 (R+0.011) where d=10mm and P=0.89b
W000 (L- 0.004) Where d=10mm and P=0.498b. Work in metric to 3 decimal places and watch your units
Don't use approximations found on some American sites. They will not get you through Geochecker. You may see P given as NP and R as NR, take them as the same.
For once Wikipedia won't help!
