Okay, so if you're trying to figure something like this out quickly, look at the exponent number, and see if it's positive or negative. If it's positive, move the decimal in your number to the right. If it's negative, move the decimal in your number to the left. Easy trick my science teacher taught me :)
In this case, it's going to be .12 x 10 -3 because if you do that decimal trick, you move the decimal three places. .00012
