| 1406860 | 2015-08-17 23:30:00 | Should go back to measuring it in how many "Cheery-pip ol' chaps" are received per 317 handspans or something, perhaps. Litres/100km is a simple, and broadly averaged rating that is relatively simple to test in a consistent manner between vehicles under controlled conditions. km/litre is more suited to establishing remaining range based on a known fuel quantity, as long as the km/litre value used is averaged across a sufficiently broad sample range, and it fluctuates more significantly (relatively) over short periods. Its really just what we are used to. Us old farts know that 20mpg is bad, 40 mpg is excellent . We can relate to mpg & sort of know approx what mpg our size car should get Litres/100km is something we cant relate to, because (being honest) we havnt tried Not that manufactures efficiency claims pan out in reality :p |

| 1406862 | 2015-08-17 23:43:00 | It's an easy(ish) conversion either way just divide 100 by either and you get the other. E.G. 100/ 50 km/L = 2L/100km 100/ 2 L/100km = 50 km/L Now if only those were real numbers for my car. More like on a good trip 650km from 60L = 10.8 km/L 100/ 10.8km/L = 9.26L/100km 100/ 9.26L/100km = 10.8 km/L |

| 1406863 | 2015-08-19 04:37:00 | Divide the km by the litres and multiply by 2.83, = mpg. :-) | BobM (1138) | ||
| 1406864 | 2015-08-19 05:59:00 | Just got home and had a wine..... to bluddy complicated for me. I just know that you put money in one end and distance comes out of the other end. Ken :) |

| 1406865 | 2015-08-19 07:55:00 | You can convert. My cars petrol gauge doesn't work. So, who cares, it wasn't that accurate anyway. I fill it and get about 500 kms to a tank. Tank takes 50 litres. I fill again before it reaches 500. Pretty simple really. Long trips, it would do a bit better, short hops, a bit worse.... Near enough for me. |

| 1406867 | 2015-08-19 10:48:00 | I frequently use the Torque Pro App (from Google Playstore (play.google.com)) on my mobile connected via bluetooth to a OBD2 ELM 27 (goo.gl) adapter that lives on my car's OBD2 port to the ECU. Can calculate real-time fuel consumption and fuel flow rates, trims, fuel cost, etc in imperial and metric (plus many other sensor data calc's). Interestingly can calculate "instantaneous" fuel consumption. So if coasting at 60 km/hr the mpg/kpl is about 6x than say if pedal depressed at that same speed. Can log it all as well, and map it on Google map and correlate with other sensor parameters (timing, boost, load, speed, TPS, temp's, volts, etc) to upload/save online or spreadsheet. So can get numbers for short cold cruise to long cruise and compare. Has shown a bit of difference in consumption. Can also set verbal alarms when thresholds are reached for any sensor data, and deploy custom scripts if needed to fine tune calculations. I believe the app has made me save fuel, by knowing when to coast on certain roads at certain speeds. |
