Dear convert-me.com forum visitors,

Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.

All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on convert-me.com FaceBook page

Thank you for being with us and sorry for any inconveniences this could caused.

converting from % to

Postby tt27 » Sun Jun 19, 2005 11:02 pm

I need help converting % to ppm. I'm reading a report where the amount of phosphate in soil is listed in terms such as .07% and .26% (as a percentage of the original weight - I don't know what that was, but I will find out) and I need this in parts per million. I know for a fact having working in the region in question that the ppm could be between 50 and 1500 or 100 and 2000 for example.

Probably the weight was something like .2 milligrams originally.

The work was done using a continuous flow analyzer.

I have no idea how to convert this but I need to know as soon as possible for a publication.

Any help would be great

A percent is simply a "part per hundred" so there are 10000 parts per million in a part per hundred. Move the decimal four places to the right
1/100 = 10,000 / 1,000,000
1% = 10,000 ppm

1.0 % = 10,000 PPM. You can follow this to covert % to PPM
