Since it's an inversion, the same operation works in both directions. So the 12, 11 and 10 l/100 mentioned above, become 19.6, 21.4 and 23.5 MPG respectively. As a simple mental calculation, remember that the two scales are approximately equal at 15. 15l/100=15MPG. Away from this number, they go in opposite directions, so 7.5l/100= about 30MPG (31.4 really) and 7.5MPG also equals 31.4l/100. GF
