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#
