Micrometer Inside

Can Micrometer measure the diameter inside of a cylinder?

how to make an improvised inside caliper, outside caliper and micrometer caliper?

please improve me... i really need the steps on how to make an improvised caliper... Thanks! God...
I judgement you could make them but you can get these things online or even at a hardware store (like harbor transportation) for like $10 and they will be FAR more accurate than anything you could...
