To calculate fuel economy, divide the distance travelled since the tank was full by the number of imperial gallons it takes to fill the car again. 36L = 7.9 Gallons, 1L = 0.22 Gallons (see Google's conversion thingy)
Tank Capacity
While not strictly related to fuel economy, this is a common question on the forums. The 'offical' tank capacity of an elise is 36L, however brimming a completely empty elise can take up to 45L.
Fuel Guage
S1
The fuel guage on an S1 elise is hopelessly unreliable. On the S1, there is a digital readout which displays: Full>34L>33L>32L...11L>Refill. This can change by as much as 6L on a long corner, but 'Refill' normally means you have about 10-15% capacity remaining (good for about 30 miles of steady driving).
S2
Early S2 gauge is still a number read out and is better than the S1 gauge as it will give you a good idea how much fuel is in the car, but just displays REFILL at 6lts.
The Later (Cir 04) S2 fuel gauge is a simple 5 segment display which obscures erratic readings simply by having a less granular display.
