Thanks for replying so quickly. I noticed that the book was published in the US but some American books do use grams and others don't. I tried Amazon but there was no option to look inside. Another option would be to download a free sample of the kindle version. As you said, all a bit of a faff.
There might be other circumstances where only owners would have the answer, for example, does the naan bread recipe use a hob or oven, does the sourdough recipe explain how to make a poolish or is it a quicker version? This kind of info might help you to decide whether to buy the book or not. I think an option to post questions about books would be useful.
