I am new to blender and currently trying to learn modeling techniques. I would like to change a square into cylinder. From what I've read the easiest way would be to use the array modifier and warp it around a bezier circle and then extrude that object. But I was wondering if there are any tutorials on how to do this using only transforms and only a few subdivides....To be specific, I'm trying to make a pillar object from a cube

$\begingroup$ @LeonCheung not so much duplicate as related and pertinent, good to reference here. $\endgroup$ – StarWeaver Dec 7 '14 at 13:50

I took the liberty to simplify the provided answers.
Leon Cheung-method:
Bevel Ctrl+B edges and use Clamp Overlap C while beveling.
Example:
stacker-method:
Enable LoopTools Addon that comes with Blender.
Then, use: W > LoopTools > Circle - Even though sometimes you need to manually adjust some angles.

Method 1
Starting with a scaled default cube you could add a loop cuts along all axis' Ctrl-R like so:
Then select the middle loop cut ans scale it S
Open the specials menu W and select LoopTools/Circle Note that the Looptools must be enabled in the User Preferences / Addon
Result with a Subsurf Modifier added:
Method 2
(Suggested by Leon Cheung) Select the edges of the scaled cube like so:
Press Ctrl-B for Bevel adjust the radius by moving the mouse and add cuts by turning the mouse wheel.
Result after adding and scaling a loop cut around z-axis and sub-surfing:

$\begingroup$ Could also do scale to circle, I believe the key is shift+alt+S, but I am not entirely sure. $\endgroup$ – PGmath Dec 6 '14 at 12:40

$\begingroup$ @user1894167 lol, I misread your question and thought I've read pillow but you were asking for pillar. $\endgroup$ – stacker Dec 7 '14 at 12:03

$\begingroup$ @stacker, i just didnt subsurf and added more bevel sections to your method to get a pillar $\endgroup$ – Anoop Alex Dec 7 '14 at 15:50

Here's how I would go to create a cylinder:
Here's my cube;
I add a Subdivision Surface modifier. (change the number of divisions based on how smooth you want your cylinder to look.
Here is what the cube now looks like.
Hit Tab to go into edit mode and select the top and bottom faces (edge select)
Hit N to open the properties window. look for the Mean Crease option under Transform. Set it all the way up (1.00).
Here's what it'll look like.
Just Tab out of edit made and you've got a wonderful cylinder. (apply the subdivision surface if needed.)

$\begingroup$ Thanks. That looks like a better way of doing it just using transforms and subdiv like i wanted. $\endgroup$ – Anoop Alex Dec 7 '14 at 5:20

1$\begingroup$ @user1894167 I am sorry but this method does not produce a cylinder. Subsurfaced surfaces are not round - the subsurfaced cube is not a sphere nor this is a cylinder. The bevel or verts-to-circle are both accurate methods. $\endgroup$ – Jaroslav Jerryno Novotny Dec 7 '14 at 16:30

$\begingroup$ @user1894167 I agree with Jerryno, the final result is not strictly a cylinder. Whatever, it would be okay assuming you needn't a perfect one. $\endgroup$ – Leon Cheung Dec 7 '14 at 18:42
