# Thread: "off by 10 percent"

1. ## "off by 10 percent"

Hi,

I have heard people say "the measurement is probably off by 10 percent"

But if I want to specify it is more or less. Can I say "...........is over / under by 10 percent"?

Or how else would you say it?

Thank you!

2. ## Re: "off by 10 percent"

I have seen something like "the accuracy is plus/minus 10 percent".

Not a teacher.

3. ## Re: "off by 10 percent"

For me, both "over/under" and "plus/minus" work.

4. ## Re: "off by 10 percent"

How about the measurement is out by over/under 10%?

Something might be out of tolerance or out of spec, but I wouldn't say that a measurement was "out."

Perhaps Tdol said so according to the following definition quoted from the Oxford dictionary.

out
■ adv., prep.
21 ～ (in sth) not correct or exact; wrong:
The estimate was out by more than \$100.

Not a teacher.

In AmE, it would be "off," not "out."

8. ## Re: "off by 10 percent"

Either would work for me.
