### How to calculate log base 2 using a scientific calculator?

in a scientific calculator there actually 2 buttons are for Logarithm calculation.

1. "log" button: is to calculate log base 10 (known as Common Logarithm)
2. "ln" button  : is to calculate log base e   (known as Natural Logarithm)

now to calculate log base 2, you can use any of these two, but  whichever, you gonna need to convert it into base 2.

You can do this by dividing your result by the "log" or "ln" of base 2.

e.g:
If you to calculate log(x) base 2, then calculate log(x) base 10 then divide it by log2 or to calculate  ln(x) base 2, do it with base 10 then divide it by ln2.

example calculation:
log8 base 2 is 3. using calculator is should be log8 base 10 / log2 .

thank you :)

1. great idea, thanks buddy

1. most welcome :)

2. wow! thank you!

3. Man you just save me

Also correct some language written.

Thank you

1. happy to help, pa'ji :)
but what to correct?

2. "You can do this by dividing your result by the "log" or "ln" of base 2" ...should be "You can do this by dividing your result by the "log" or "ln" of 2 (not base 2)

4. ahh thanks for all the detail man

8. Thank You bro, You awesome !

9. Thank you 4 ur awesome answer

10. that was a just a logarithm property what you did. Tell us how to make that base as 2... instead of base 10.

11. Any other method

12. good information and it is useful.@!

13. Thanks buddy

14. Thanks lot

15. thanks for the help

37. thank you.....

38. Thank you bosss... it's really helpful..

39. Thank you for this method!:)

40. You could do it very simply. ON fx-82 MS
Log2(101) = log 101 / log 2 = 6.65

41. Thanks a lot
