First convert 10,272kB to MB by dividing it by 1000:

10,272kB/1000=10.272MB

Then we can calculate how much space does one page take:

10.272MB/300=0.03424MB

After that we can finally calculate how many pages does one megabyte require

1MB/0.03424MB=29.2

So around ~30 pages/MB.

Ok the above math doesn t make any sense so i will re ask hopefully someboday can get the math right : (

How many pages equal 1 mb with standard margins of 0,25 on all 4 sides of the page s ?

Maybe this will make the math easyier ; how many pages are in a 300 mb sized e book ?  ?

Hum ok so 1 page = about 11.7 mb correct is that right pretty close always wondered  :  )

How did you end up in this result? I stated that one page is around 0.03424MB

...

Then we can calculate how much space does one page take:

10.272MB/300=0.03424MB

...

So in order to calculate how many pages are in 300MB ebook we simply divide one page size with that size:

300MB/0.03424MB = 8 761,68 =  ~8 761 pages.

300MB can container 8761 pages

and one page takes 0.03424MB of space.

This isn't "exact" answer because there are other factors to consider such as metadata which can vary per page.

It is your math not mine and don t think a 300 page book equals 8; 761 pages hum ?

Maybe i need to count the number of lines on a page then  count the number of characters / spaces per line x 2 numbers then divide that by 300

and that will get the correct number of pages maybe ?

I don t get your new math makes no sense  :  (

Ok 63 lines on a page then 70 characters/ spaces across on 1 line.

So 63 x 70 = 4,410 characters total  so guess the next question is how many letters/ numbers and spaces = 1 mb then maybe divide that number by 300

and that should be the final answer ?            Amazing how hard to figure out the correct answer dont think its 8 thousand plus as suggested above .

Wonder is i google how many characters = 1 mb would that give me an answer hum ?   -  later

The math doesn t add up their aren t 8 thousand plus pages in a 300 mb book just googled for some math never understood the new math of above.

1 mb = 1,020,000 characters so  63 x 70 = 4,440  which equals 23 pages then divide 23 by 300 = 76 pages . .

Which breaks down to 23 pages = 1 mb  whew .

You're missing the implication of your own result. If 23 pages are stored in 1 MB, 300 times as many pages will be stored in 300 MB. 23 x 300 = 6900 pages.

However Slurppa's original answer is correct for the information you gave us. Using rounded figures to make the calculation simple, you have a 300 page book, it occupies 10 MB (rounded). So of its text, 1 MB (one tenth of 10MB) will contain 30 pages (also one tenth of 300 pages as required). Slurppa calculated it precisely, the exact result per 1 MB of your book is 29.2

So if each 1MB in your book holds 29.2 pages, a file 300 MB in size (300 times as big) will hold 300 times as many pages - 300 x 29.2 = 8760 pages.

I don t know how this got off track but i have noticed that happens a lot here then i get off track two and then things get funky ouchy .

The book is 300 pages long not 300 mb and my printer is only printing out 300 pages of text with standard 0.25 margins on all 4 sides and no graphs or photos

so your math is wrong will ask at another pc help site ho hum :  (

Yes, the original e-book you have, and started using as an example, fits 300 pages in about 10 MB. So "300 pages = roughy 10 mb" is right.

I think when you asked "how many pages are in a 300 mb sized e book ?" in post #4, the 300 pages and the 300 MB got mashed together in your calculating.

It depends on the options offered by your printer. Many do have an eco mode for ink saving, that can be enabled in one of the menus in your printer's driver.
