Yeah they're right, metric system is better. It's easier to do physic calculation with it.
Here an example of the use.
Time elapsed between 2 F1 in a 100meter straight line.
Car 1: 55km/h in the exit of the turn
Car 2: 50km/h in the exit of the turn
Distance= 100meters
100km/h=27.7~m/s
car 1: 3.2sec -> 0 to 100km/h -acceleration
car 2: 3.0sec -> 0 to 100km/h -acceleration
Note: F1 doesn't have a lot of difference in the acceleration
Speed=Distance/Time running
Acceleration=Speed Difference/Time difference
D=Distance
Acceleration Displacement car 1=(27.7~m/s)/3.2sec=8.68m/s²
Acceleration Displacement car 2=(27.7~m/s)/3.0sec=9.23m/s²
Final Speed²=Initial Speed²+2*acceleration*distance
X²=15.27m/s²+2*8.68*100
car 1=44.38m/s final speed in the end of the straight=159.7km/h
X²=13.88m/s²+2*9,23*100
car 2=45.15m/s final speed in the end of the straight=162.6km/h
Distance/0.5(Initial Speed+Final speed)=Time elapsed
Time used for the straight, Car 1:
100/0.5(13.88+44.38)=3.43sec
Time used for the straight, Car 2:
100/0.5(13.88+45.38)=3.37sec
Other Factor didn't mention in the calcul:
-Chassis Aerodynamic
-Spring Setup for the track
-Gear setup
-The track
-The weather
-The driver
-The quality of the brake
-The brake setup
-Pit Strategie
-Strength of pit crew
-Car control with bad tires
-Braking Distance of the car
-Time used for the curve
-The curves tracks angle
-Track surface
-No variation in the car displacement
-Driver condition
-The amount of gaz in the car
Might be crazy for younger user, but you'll learn it at school someday.

Welcome to GTPlanet, lwm! You might want to give the GTPlanet Speed Converter a try. 
I've posted on this subject before, and as I come from a Computing/Physics background, I wholeheartedly support the prolferation of metric.
The only trouble is one of cultural change. The fact of the matter is that in motoring terms in the UK, cars measure speed in mph, distance in miles, fuel economy in mpg. Road signs are in miles and mph. Beer is served in pints.
It's getting better. Generally, fuel is sold in litres, it's getting harder to find a pint of milk, and produce is being sold by the kilo.
But until these barriers are broken down, I think making it a preference would be a sage move by Polyphony Digital.
It would make it easier if we all spoke in the same terms, but that just isn't going to happen in the near future.

I find it ironic that in British schools they teach us kids how to do distance calculation in Kilometers yet all our road distances and cars are done using Miles Per Hour and Miles to the Gallon.
Personaly I don't care which is used in GT3 but its easier for me to determine how far a car is going if its in MPH... Ontop of that I don't think the British government will ever change from Miles... too costly to do at the mo... with the current state of the NHS and all.
