Why has no person yet volunteered a confirmation of the exact arithmetic of lbf and lbm in f = m x 9.80665?
Do the exact numerical values simply have two many necessary digits to be multiplied exactly by most of us? Hint: Use (a + b) x (c + d) where the numbers ( ) with "too many digits" are expressed as sums, and each part of each sum is initially expressed in exponential form. Then, this exercise becomes tractable on many inexpensive digital calculators. Who will be the first to confirm the exact fit of lbf and lbm (as *defined* numerically) with Newton's Second Law? Or, would most of you simply prefer to trash all that is non-SI? (a perfectly respectable attitude) Eugene Mechtly
