Kilograms to Ounces Converter (kg to oz)
1 kg ≈ 35.274 oz. Convert kilograms to ounces, or to pounds and ounces for baby and parcel weights, with kg to oz and oz to kg charts.
Ounce (oz) = Kilogram (kg) × 35.2739619496
Kilogram (kg): The kilogram is the SI base unit of mass. Since 2019 it has been defined by fixing the value of the Planck constant, replacing the platinum-iridium prototype kept near Paris.
Ounce (oz): The avoirdupois ounce is 1/16 of a pound, exactly 28.349523125 grams. It is the everyday ounce for food and parcels in the US; precious metals use the heavier troy ounce.

A kilogram is about 35.27 ounces, so metric weights turn into large ounce figures quickly. That direction is useful for American cooks following European recipes, for parents given a birth weight in kilograms and for anyone comparing metric pack sizes with US ones labeled in ounces. It also helps when a parcel scale reads in kilograms but a US postal rate is set in ounces.
The first chart adds a pounds-and-ounces column, because a weight such as 3.4 kg is usually wanted as 7 lb 7.9 oz rather than 119.9 oz. The kilogram values focus on the range from a pack of butter to a newborn baby; results under a pound appear as 0 lb plus ounces.

Formula
Ounce (oz) = Kilogram (kg) × 35.2739619496
Kilogram (kg) = Ounce (oz) × 0.028349523125
Both factors come from exact definitions: 1 ounce = 0.028349523125 kilograms and 1 kilogram = 35.2739619496 ounces (shown to 12 significant digits).
Example
Two conversions worked with the same factors the converter uses:
3.4 kg × 35.2739619496 ≈ 119.931 oz
16 oz × 0.028349523125 = 0.45359237 kg

Quick mental estimate
Multiply the kilograms by 35, then add a quarter of the kilogram figure: 2 kg → 70 + 0.5 = 70.5 oz. That uses 35.25 in place of 35.274, less than 0.1% low.
Use the converter or the charts when the exact figure matters.

Frequently asked questions
How many ounces are in a kilogram?
About 35.274 oz; to ten significant figures, 35.27396195. Half a kilogram is about 17.6 oz, and since a gram is about 0.035 oz, every 100 g adds roughly 3.5 oz.
How do I turn a baby's weight in kilograms into pounds and ounces?
Use the pounds-and-ounces column of the first chart, or type the weight into the converter and split the pounds: 3.4 kg comes to 7 lb 7.9 oz. Multiply the decimal part of the pounds by 16 to get the ounces.
How does a 250 g pack of butter compare with US sticks?
It weighs about 8.8 oz, a little more than two US sticks of 4 oz each. A recipe that calls for a European block can be followed with two sticks plus about 0.8 oz (roughly 23 g) of butter.
How precise is the result?
The converter uses the exact definitions above with browser floating-point arithmetic and shows up to 12 significant digits. The charts round to four decimal places for reading.
