JPG compression info please

Hi,
I'm trying to find the relationship between Photoshop's jpg compression numbers and PSP's % jpg compression.

i.e. - Does a 10% PSP jpg compression equal a 10 for PS?

There has to be a chart somewhere.

Thanks in advance.

I don't know about photoshop, but jpegs tend to be compressed on a 1-100 scale. Most packages, like PSP, use it as a measure of "compression" from 0 (looks good, big size) to 100 (looks awful, bu small). Some others reverse this and have a measure of "quality" where 0 is the worst and 100 is the best. To convert from one to the other, just subtract from 100.

Thanks Chris,
Most online print shops talk PS and request a 10 compression. I'll just do a test to figure out how that compares to a PSP % compression.
