Increasing by a magnitude of 10.

The initial value was 1 and the final value is 10.
We can say it grew by 900%.
It is 10 times larger.
It grew by a magnitude of 10.
Which one is better?
Is there a better way to describe it?
Thank you.

I'm not a math guy, but engineers and scientists use the expression, "orders of magnitude" when talking about powers of ten. In your case, I'd say it grew by one order of magnitude. To my ear, "It grew by 900%" is bizarre, but I suppose it's correct.

  • " If you're looking for an exact figure , and the initial and final values are 1 and 9 , "one order of magnitude" will not work.

To my ear, "It grew by 900%" is bizarre, but I suppose it's correct. (In "It grew by X," X is the amount which is added, as you know.)

"It increased tenfold" is another common expression,
