Vitamin E Concentration

I read that one ounce of pure alpha tocopherol is equivalent to 28,000 International Units.

Solgar's Liquid Vitamin E has 10,000 per ounce, which implies it's concentration is 36%.

Lotion Crafter's Vitamin E concentration is 95%. This implies that to get 400 IU, one should consume 1/66 ounces.

One drop of Solgar's Liquid Vitamin E has 100 IU, so one drop of Lotion Crafter has 263 IU.

This is all an approximation. There are probably some inaccuracies because Lotion Crafter and Solgar's contain other forms of tocopherols than alpha as well.

Swanson's Maximum-Strength Gamma Tocopherol Vitamin E has 1173 mg vitamin E per pill (750 gamma, 290 delta and beta, 133 alpha)
Unique E has 698 mg
Carlson's E-Gems Plus 400 IU has 336 mg

These are weight measures. I don't know if more weight equals more volume here because it's mix of substances (tocopherols).
