Is there a standard conversation rate for Microsoft Word pages to actual book pages? Say I have 50 M-Word pages (in the standard 12 New Courier double spaced format) - how many pages will this be as an actual printed book? Or,
how many pages will 10,000 words likely be as a published book?

Optional opinion question:
is 10,000 words too long for a 1st chapter?

Thanks!
Best,
Jeff
