Ounces are used in US cooking and postal measurements. This calculator multiplies your kilogram value by 35.274 to give the precise avoirdupois ounce equivalent.

How It Works

The formula is kg × 35.274 = ounces. This conversion factor is derived from the exact definition of the avoirdupois ounce: 1 ounce = 28.349523125 grams exactly, so dividing 1,000 grams (one kilogram) by 28.349523125 gives 35.274 ounces. This calculator uses the avoirdupois ounce — the standard for everyday weights in the US — not the troy ounce used for precious metals. Common practical uses include reading US food packaging (products labelled in ounces when produced or weighed in kilograms at origin), international shipping (carriers may quote weight in kg while recipients expect ounces on labels), and following US recipes where ingredient quantities are given in ounces.

What is the difference between ounces and fluid ounces?
Ounces (oz) measure weight or mass. Fluid ounces (fl oz) measure volume. This calculator converts kilograms to weight ounces only — not fluid ounces. The two units serve different purposes and should not be used interchangeably. One US fluid ounce of water weighs approximately 1.04 oz, but for other liquids the values differ.
