Oranges come in quite a range of sizes and are picked in varying states of ripeness and are often stored in less than perfect conditions. A range of 50 to 80 milligrams would probably cover most of the fruit you are likely to find.

According to the USDA data base on Vitamin C, oranges contain 95.8 mg.

USDA National Nutrient Database for Standard Reference, Release 18

.

[DanSco]

The USDA data base shows the amount of orange as 1 cup. That number will only be valid when 1 orange = 1 cup.

Hi Dan,

Do the math!
If 180 gms of orange contain 95.8 mg of Vit C.
Then, for example, 135 gm of orange would contain 71.85 mg of Vit C.
Or, 225 gm of orange would contain 119.75 mg.

Cups should work the same way. 3/4ths of a cup should also contain 71.85 mg.

I think it is a most valid general guide.
