Appendix D: Unit Conversions from SI System to English System
The following are useful when converting from the SI system to the English system:
| Length: | 1 m = 100 cm = 39.7 in. |
| 1 m = 3.28 ft | |
| 1 m = 6.22 × 10−-4 mile | |
| Area: | 1 m2 = 0.386 × 10−-6 mile2 |
| 1 m2 = 1550 in.2 | |
| 1 cm2 = 0.155 in.2 | |
| Volume: | 1 m3 = 35.3 ft3 |
| Linear speed: | 1 m/s = 100 cm/s = 3.28 ft/s |
| 1 m/s = 2.237 mph | |
| 1 m/s = 39.37 in./s | |
| Rotational speed: | 1 rad/s = 9.55 rev/min = 57.3 deg/s |
| Force: | 1 N = 0.225 lb |
| Power: | 1 kW = 1000 W = 1.34 hp |
| Torque: | 1 N-m = 0.737 lb |
| Magnetic flux: | 1 Wb = 108 lines = 108 maxwells |
| 1 Wb = 105 kilolines | |
| Magnetic flux density: | 1 T = 6.45 × 104/line/in2 |
| 1 T = 64.5 kilolines/in ... |
