Questions

How do I convert l/100km to mpg? Type “6.5 l/100km in mpg”. Ratio knows the two run in opposite directions, so it divides rather than multiplies.

Can it convert currency too? Yes: “450 km at 6.5 l/100km at 1.8 usd/l in eur” uses today's rate.

What about time zones on the way? “10:00 London + 11 h in Tokyo” gives the arrival time, and “jet lag London to Tokyo” the difference and roughly how long to adjust.
