The misleading, wasteful way we measure gas mileage, explained
The misleading, wasteful way we measure gas mileage, explained
Good point, but GPHM has more syllables, and GPM makes it sound small.
Maybe 50, 25, 15, and 10 MPG could be expressed as 0.02, 0.04, <0.07, and 0,1 GPM.
I was doing the metric equivalent.
The problem is mLs and ounces sound too small.
The good thing about 100 is that in turns mLs and ounces into liters and pounds, or gallons, as the case may be;
but that 100—I like units more than x-number-of-units as the basis of expression.
I guess its GPHM, LPHKM, GPH, and LPH, until we come up with something better.
Then we have wp:natural gas vehicles and wp:miles per gallon gasoline equivalent, as LNG, CNG, and electric will probably become more common.
If 33.40 kilowatt-hours/mile ≈ 74.71 Mj/km
then if an electric car had an MPG equivalent of 40,
it’d be 0.835 kilowatt-hours/mile ≈ 1.87 Mj/km
“x ℓ/100”
maybe.
maybe “x mL/km” (“x milliliters/km”)—as in “80 mL/km”
or
maybe “x kL/Mm” (“x kiloliters/megameters”)—as in 0.8 kL or 800ℓ/Mm"
I have to think about it.
I wish that were used. But instead we get this inverse, L/100 km.
Edit: after reading the article, apparently this is actually better. Even though km/L might seem easier to work with, it is misleading in terms of how you compare two vehicles.
It’s why the 2007 Chevy Tahoe Hybrid won a green car award. It may have been a measley 21MPG city (11.2 L/100km, 4.8gal/100mi), but that was 30% better than previous models.
Notably, the US DOE shows gal/100mi on their fuel economy website already. www.fueleconomy.gov/…/2007_Chevrolet_Tahoe.shtml www.fueleconomy.gov/…/2008_Chevrolet_Tahoe.shtml
