Approximately 0.035, or more accurately about 0.035274

Explanation:

We can get a rough approximation starting with the facts:
1. One kilogram is about 2.2 pounds.
2. One pound is 16 ounces.
3. One kilogram is 1000 grams.

So the number of ounces in a kilogram is about 2.2 * 16 = 35.2 and in a gram is therefore about 35/1000 = 0.035

For a much more accurate approximation, start with:
1. One pound is exactly 453.59237 grams.
2. One pound is exactly 16 ounces.

So the number of grams in an ounce is exactly:

453.59237 / 16 = 28.349523125

The number of ounces in a gram is the reciprocal of this:

1/28.349523125 ~~ 0.035274
