Well, that was a certain fraction of the distance from the north to the south poles along a particular line of longitude. I forget both the fraction and the line of longitude. The modern meter is the wavelength of a certain color of light emitted from the most common isotope of tungsten heated to a particular temperature. Nice, handy references. But, for those stuck on the English system of measurement, we just need to remember that a meter is 39.37 inches, or a tad more than a yard. Got your rods and furlongs straight? How about cups and bushels? I like the metric system myself. mcneely > > > On 6/29/2012 8:19 AM, mcneely4@cox.net wrote: > > Just as a comment, boy, the SE (metric system) is sure easier than our antiquated system. thanks for reminding us, Scott. mcneely > > > > ---- Scott Daniel - Turbovans <scottdaniel@TURBOVANS.COM> wrote: > >> On 6/28/2012 9:07 PM, Tom Hargrave wrote: > >>> 2.3 kg of carbon per liter burned > >> 2.3 kg is roughly 5.06 pounds > >> Something is missing or not stated right as it does not seem that there > >> are 5 lbs of carbon in one liter of fuel. > >> if gas weighs around 6 lbs per gal . > >> that means a liter of gas weights around 1.5 lbs. > >> pretty hard to get 5 lbs of carbon out of 1.5 lbs of gasoline I'd think. > >> > >> what pollutes more ..? > >> a 7 liter engine with an idle emissions figure of 1.0 % CO, > >> or a 1 liter engine with that same emissions spec at idle ? > >> > >> Europeans measure in grams of whatever pollutant, CO2 say, per distance > >> traveled, say grams per mile. .
