Yeah don't know how they're calculating that.I paid £30 back in 2014. It is now £10 more!
The spec on it is way off, 1L in a 7cm pan? lol

3.5*3.5*pi*14 = 539cm^3
1000cm^3 is a litre.
edit:
LOL from the image it is clearly not 14cm tall but 7cm tall. Interesting to call the height of a pan it's width from edge of one rim to the end of the handle...
So it'll be 270 cm^3 = 270ml
