1 kilogram is 35.27 oz. One kilogram is exactly 35.2739619496 ounces.
One kilogram is 35.273962 ounces. To convert kilograms to ounces, multiply by 35.273962; to go the other way, divide by 35.273962 or multiply by 0.028349523. The relation is exact but the figure is not: it is a rounding of a number that does not terminate, and it follows from NIST Handbook 44. The SI base unit of mass, defined since 2019 by fixing the Planck constant rather than by a metal cylinder in Paris.

A troy ounce is ten per cent heavier
This page uses the avoirdupois ounce, 28.349523125 g, which is the ounce on a kitchen scale and a shipping label. Gold, silver and platinum are quoted in troy ounces of 31.1034768 g. Converting a bullion weight with the ordinary factor understates it by about ten per cent.

What is a kilogram?
The SI base unit of mass, defined since 2019 by fixing the Planck constant rather than by a metal cylinder in Paris.
