Kilograms ↔ ounces

The common ounce (avoirdupois) equals 28.3495 g. That means 1 kg = 35.27396 oz and 1 lb = 16 oz. This converter flips between them with kilograms as the anchor.

How the conversion works

$m_{oz} = m_{kg} / 0.0283495$
$m_{kg} = m_{oz} \\times 0.0283495$
$m_{lb} = m_{oz} / 16$

Units and conversions

Unit	Symbol	Relation to kg
Kilogram	kg	base
Ounce (avoirdupois)	oz	$1\\,\\text{oz} = 0.0283495\\,\\text{kg}$
Pound	lb	$1\\,\\text{lb} = 0.453592\\,\\text{kg}$

Worked examples

1 kg → oz
$1 / 0.0283495 \\approx 35.27396\\,\\text{oz}$ .
16 oz → kg
$16 \\times 0.0283495 \\approx 0.453592\\,\\text{kg}$ .
10 lb → kg
$10 \\times 0.453592 \\approx 4.53592\\,\\text{kg}$ .

Tips and pitfalls

Use ounces for recipes and postal limits; switch to pounds for gym or shipping work.
Keep four decimals for lab precision; two decimals are enough for cooking.
Mass cannot be negative; the calculator blocks negative entries.
