    Ok so if I number, lets say A which has error U. Now if I divide this number by say...5, what is the new error?

    I'm pretty sure the error stays the same but I just want to quickly verify this, thanks.

    When you say "Error U", is that the % error, the fractional error, or the absolute error. It matters.

    Absolute.

    The % and fractional error stays the same.
    If you measure a value of X as say, 100 and give it as 100 +or- 5 (a 5% error)
    You then calculate some quantity Y that is X divided by 5.
    Is the value of Y = 20 +or- 5, (now a 25% error) or 20 +or- 1 (still a 5% error)?

    I was right then, I think I worded my answer to your question wrongly, while it's an absolute error I have at the moment, I am aware when I'm diving, I need to convert it to a % error, so maybe I should have just said it's a % error.
