I have some 5 gallon extract recipes and was wondering it there are any programs out there that if I put in ingredients for 5 gallon batch that then it will convert it down to a mr beer fermenter size batch?
5 gallon recipes scaled down to mr beer fermenter ANY Programs that do it

I am guessing Beersmith does this. I scale 5 gallon all grain recipes on Beersmith frequently. You can also do good ol fashion math. Divide the quantity of the ingredient by 5, multiply that number by 2 (or 3, not sure what the 'Mr. Beer' fermenter size is..) You're just figuring out how much per gallon for each ingredient and then multiplying to your desired gallons...

You can do it on brewtoad.com, it's free. but, assuming you're doing 2 gallon batches, all you really need to do is multiply each ingredient by 0.4, or just do what lukeziegler said, you'll get the same number.

2.5 gallons is 1/2 of 5 gallons. So you'd use 0.5 instead.

It would be 0.5 for 2.5 gallons. At a 2.5 gallon batch your are just halving your ingredients. You probably still want to pitch the full yeast amount (or real close to it.)

Aren't the mr. beer barrels made for 2 gallon batches? If the container holds 2.5 gallons, you definitely want to leave that half gallon as head-space
I never did one,but I see it & think it should have 1/2 gallon head space myself.
Divide it. That's all.
for a half batch, divide by half.
for a 1 gallon batch, a 1/5 size, divide by 1/5.
It's simple math for all sized batches.

Just in case you are wondering, you should scale your ingredients by weight.
