When doing metric-to-imperial (x/1.61) conversions and vice versa, remember that your conversion from the value with one decimal place may not always be accurate! The game actually uses multiple decimal places for top speed values (without Pro Kit upgrades; set in metric. This is assuming that the car does not have a fake speed multiplier of any sort):
 * for every xx0.1		=	xx0.07143 (0 + 1/14)
 * for every xx1.5 or xx1.6	=	xx1.50000 (1 + 7/14)
 * for every xx2.9 or xx3.0	=	xx2.92857 (2 + 13/14)
 * for every xx4.4		=	xx4.35714 (4 + 5/14)
 * for every xx5.8		=	xx5.78571 (5 + 11/14)
 * for every xx7.2 or xx7.3	=	xx7.21429 (7 + 3/14)
 * for every xx8.6 or xx8.7	= 	xx8.64286 (8 + 9/14)

For nitro values: and so on...
 * 17.1			=	17.143 (240/14)
 * 18.6			=	18.571 (260/14)
 * 20.0			=	20.000 (280/14)
 * 21.4			=	21.429 (300/14)
 * 22.9			=	22.857 (320/14)
 * 24.3			=	24.286 (340/14)
 * 25.7			=	25.714 (360/14)
 * 27.2			=	27.143 (380/14)
 * 28.6			=	28.571 (400/14)
 * 30.0			=	30.000 (420/14)
 * 31.4			=	31.429 (440/14)
 * 32.9			=	32.857 (460/14)
 * 34.3			=	34.286 (480/14)
 * 35.7			=	35.714 (500/14)
 * 37.2			=	37.143 (520/14)
 * 50.0			=	50.000 (700/14)
 * 51.4			=	51.429 (720/14)

Let's take the Lamborghini Aventador LP 700-4 at MAX+PRO+Tuning Kit. Its top speed stat is shown as 261.8 mph (421.6 km/h). What is it actually? 261.801 mph (421.500 km/h).

Another example: Ferrari 308 GTS at stock. Top speed stat is shown as 160.6 mph (258.6 km/h). What is it actually? 160.648 mph (258.643 km/h).
