Length:                     1 mm = 0.03937 in
                            1 m = 0.00003937 in
1 in = 25.4 mm
1 in = 25400 m

Temperature:                (9/5 x °C) + 32 = °F
5/9 x (°F – 32) = °C

Force:                      1 N = 3.5957 ozf
                            1 N = 0.2247 lbf
1 ozf = 0.2781 N
1 lbf = 4.4497 N

Moment:                     1 Nm = 141.5612 ozf in
                            1 Nm = 8.8478 lbf in
1 ozf in = 0.007064 Nm
1 lbf in = 0.1130 Nm

International material designations:

100 Cr 6 (1.2067 / 1.3505)  corresponds to  AISI L3 / AISI E 52100
X155 CrVMo 12 1 (1.2379)    corresponds to  AISI Type D2 Tool Steel
X90 CrMoV 18 (1.4112)       corresponds to  AISI 440B
