GENERAL INFORMATION AND MAINTENANCE 1-81
ENGLISH TO METRIC CONVERSION: FORCE
Force is presently measured in pounds (Ibs.). This type of measurement is used to measure spring pressure, specifically
how many pounds it takes to compress a spring. Our present force unit (the pound) will be replaced in SI metric
measurements by the Newton (N). This term will eventually see use in specifications for electric motor brush spring
pressures, valve spring pressures, etc.
To convert pounds (Ibs.) to Newton (N): multiply the number of Ibs. by 4.45
