For example, using an extractant (e.g., Mehlich-III) to extract a soil sample can obtain a value of a specific nutrient such as phosphorus, e.g., 50 ppm. This value means that the tested soil contains 50 mg of Mehlich-III-extractable phosphorus per kg of soil.
180 mg vitamin E at dl-alpha / 0.45 = 400 IU vitamin E. If it’s a naturally-sourced vitamin E, you will see it called “d-alpha.” If you see “d-alpha” on the label, just multiply the IU by 0.67. For example: 400 IU of vitamin E as d-alpha * 0.67 = 268 mg vitamin E. To go the other way you just divide:

Percent to ppm converter How to convert ppm to percent. 1% = 1/100. 1ppm = 1/1000000. So. 1ppm = 0.0001%. So to convert from ppm to percent, divide the ppm by 10000: x (%) = x (ppm) / 10000 . Example: find how many percent are in 300ppm. x (%) = 300ppm / 10000 = 0.03%. ppm to percent conversion table
