The kilogram (kg) is the SI base unit of mass, while the ounce (oz) is the smallest everyday weight unit of the US customary system, at one sixteenth of a pound. Cooks meet this conversion when adapting metric recipes to US measures, and it also turns up with coffee bags, newborn weights, and postal scales that straddle the two systems.
One kilogram equals 35.274 oz. A 250 g (0.25 kg) block of butter is 0.25 × 35.274 = 8.82 oz, and 5 kg comes to 176.37 oz — or 11 lb 0.4 oz once you group each 16 oz into a pound. Using 35 oz per kilogram for mental math lands only about 0.8% low, close enough for most kitchen work.
