BMW Fuel consumption
gauge in litres per 100 kilometers.
The US gauge is calibrated in MPG,
in reverse.
I have conversions both to and from US
units.
**EUROPEAN and METRIC to US **
These are for
converting from European literature, press releases and web sites.
They also are for converting from gauges and dashboard computers.
**Horsepower** Multiply
by 0.986 (Europe uses a slightly different standard than SAE).
**Newton-meters
to foot-pounds** Multiply by 0.7376.
**Fuel
Economy: Litres/100 km to MPG** Divide 235 (235.2146) by l/100
km. Example to convert 10.0 litres/100 km to MPG: 235 / 10.0 = 23.5
MPG.
**Acceleration
0 - 100 km/h to 0 - 60 MPH** Multiply time by 0.95. 100 km/h
is 62.1 MPH. It takes longer to hit 100 km/h than 60 MPH. The energy
required for acceleration varies as the square of the velocity. Actually
0.9324 is the square of (60/62.1). Unlike the other conversions,
acceleration values will vary from this calculation if there is a
shift point between these two speeds. That's why 0.95 is closer to
reality and unlike the other figures is somewhat variable. Mercedes
specified some Diesel acceleration times for 0 - 55 MPH, for which
you need to multiply by about 1.19 to get the time to 60 MPH.
**Kilometers
to Miles or km/h to MPH** Multiply by 0.621 (0.6213711922),
or divide by 1.61 (1.609344).
**Litres
to US Gallons** Multiply by 0.264 (0.2641720524),
or divide by 3.785 (3.785411784).
US to EUROPEAN and METRIC
These are for
Europeans to convert from US literature and my websites.
**Horsepower** Multiply
by 1.014 (Europe uses a slightly different standard than SAE).
**Foot-pounds** to
**Newton-meters **Multiply by 1.3558
**Fuel
Economy: MPG to Litres/100 km ** Divide 235 (235.2146)
by MPG. Example to convert 23.5 MPG to litres/100 km: 235
/ 23.5 = 10.0 l/100 km.
**Acceleration
time 0 - 60 MPH to 0 - 100 km/h ** Multiply time by 1.05.
60 MPH is only 96.6 km/h. The energy required for acceleration
varies as the square of the velocity. This factor is the square of
speed ratio, or (96.6/100)^2, or 1.0725. Unlike the other conversions,
acceleration values will vary from this calculation if there is a
shift point between these two speeds, so I've found it closer to
1.05 in most cases.
**Miles
to Kilometers and MPH to km/h** Multiply by 1.61 (1.609344),
or divide by 0.621
(0.6213711922).
