Fuel Economy MPG/KPG/KPL

[GoldOxide_imp]

If you stretch it a bit we have five - Sweden uses the "mil" which represents ten kilometers. The Swedish "mil" started off 1699, representing 6000 fathoms or 10,7 km. The "mil" was 1/2 of the king's stipulated max distance to between inns with horses for change etc. The "mil" survived when Sweden finally went metric in 1899, but was adjusted accordingly to signify 10,0 km. To this day we tend to talk about travelling distances in "mil" rather than kilometers.

The French came up with the most logical solution: get rid off kings, and with their eccentric units based on their anatomy, their state of mind or the strength of their horses.

Then you go to the UK, and your vehicle shows your fuel economy in MPG, but you refill in liters :-?

(Although I have to say, when you work in mechanical design and you need precision, "imperial bolts" beat any metric standard.)

lol - I don't understand what that means.

Perhaps he means that there are even finer treads available in imperial bolts than in the fine metric treads ?

Straight from Wiki

British Standard Fine (BSF) is a screw thread form, as a fine-pitch alternative to British Standard Whitworth (BSW) thread. It was used for steel bolts and nuts on much British machinery, including cars, prior to adoption of Unified, and later Metric, standards. For highly stressed conditions, especially in motorcycles, a finer thread, British Standard Cycle (BSC), was used as well.

Is not only the finer threads: for the same diameter, on metric standards usualy you have several options for the length, in 5mm increments. On Imperial, you have increments in 1/16" (approx 1.6mm).

So you can get your "grip length" matched to your assembly without too much or too little protrusion.

For example: google "NAS Bolt 1306". You will see that thread length is always the same for a particular diameter. But for "grip length" (i.e the "shank" part) you have endless options.

There are no limitations for hardware manufactured under the metric system anymore than the imperial system.

Tis true, tis true. My '52 MG TD engine has all metric threaded bolts because they purchased the engine design from France. To satisfy the factory, and presumably the wider spannering public, the bolt heads were made Whitworth. That has caught a few people out.

Of course! You can always use your own standards, or design a specific bolt for a particular need. That's what some F1 teams do, as well as aerospace industry (like airbus: they use metric) and military industry. But that's an expensive route.

Most racing teams in Europe end up with a mix: metric where they can, imperial where they have to. For example: most good quality swaged spherical joints used for suspension systems are aerospace standards, again, only in imperial... or hard/expensive to get (from airbus' suppliers).

Had to fill up today. According to my Trip B I had gone 176.7 mi, on 2.9 gals of gas and averaged 60.9 mpg

So I zeroed trip B. Filled up with gas without looking at the pump. Turned around I had put in 2.92 gals of gas and the calculator in my phone said I averaged 60.5 mpg.

That's pretty darn accurate if you ask me.

These are U.S. gallons and miles.

That is excellent economy Ferret. Do you recall your average speed throughout the tank of fuel?

I find Honda average fuel consumption and range remaining calculations to be very reliable (CB1100, NC750X, CRF1000).

Some other owners express different experiences and not sure why the variance.

45 to 60 mph 5th and 6th gear on country curvy back roads. That's how/where I normally ride on my daily rides.
