Quick formula for working out Revs Per Minute and Ratios to Road Speed.
eg: at 7,000 Rpm in top gear road speed of 300km/h
First we need to know the tyre circumference in meters:
eg: 275/40 x 20 Tyre and Wheel
work out wheel and tyre diameter first
Tyre width = 275mm
Tyre Profile = 40% x 275mm = 110mm
110mm top and bottom of the wheel =220mm
+ the Wheel diameter
(20 inches wheel dia x 25.4 = 508mm)
220 + 508 = 728mm Total wheel diameter.
x Pi (3.14159) to get the circumference = 2287mm divded by 1000 to get to meters = 2.287 meters of tyre circumference on a 275/40 x 20 tyre.
2.287m
Now the rest is simple.
RPM / Gear Ratio / Diff Ratio x Tyre Circumference x 60 / 1000 = Km/h
RPM divided by Gear Ratio divided by Diff Ratio multiplied by Tyre circumference multiplied by 60 divided by 1000 = Km/h
eg: 2200 rpm / 0.76 gear ratio / 4.10 diff ratio x 2.288 tyre circumference x 60 time / 1000 distance = 96.9 Km/h or
1000 rpm / 0.76 gear ratio / 4.10 diff ratio x 2.288 tyre circumference x 60 time / 1000 distance = 44 Km/h x 2.2 for 2200 rpm = 96.9
I hope you like this formula, its good for working out speedo change with tyre size change or for racing purposes.

Quick formula for working out Miles Per Gallon from litres per 100km.
Kms / Litres x 2.822 = M.P.G
eg: 100Kms divided by 12.5lts multiplied by 2.822 = 22.576 miles per gallon or
550kms for 68.75 litres of fuel.
550 / 68.75 x 2.822 = 22.576 mpg
