Ounces to Kilograms (oz to kg)

Common questions

How many kilograms are in an ounce?

Exactly 0.028349523125 kg. An ounce is a sixteenth of the international avoirdupois pound, and that pound has been defined as exactly 0.45359237 kg since 1959, so the factor is a definition rather than a measurement and the page prints every digit of it. The Copy result button copies the figure without the digit grouping, so it pastes straight into a spreadsheet.

What is 16 oz in kg?

0.45359237 kg, exactly, because sixteen ounces is one pound and the pound is defined in kilograms. Type 16 into the field and the answer appears with no button press. The other kitchen amounts work the same way: 4 oz is 0.1133980925 kg, 8 oz is 0.226796185 kg, 12 oz is 0.3401942775 kg and 100 oz is 2.8349523125 kg.

Is an ounce the same as a fluid ounce?

An avoirdupois ounce measures mass, while a fluid ounce measures volume. Under Volume, one US fluid ounce is exactly 29.5735295625 mL and one imperial fluid ounce exactly 28.4130625 mL. Converting volume to mass requires a supplied density applicable to the material and conditions: mass = volume × density, in matching units. Unit Converter does no density conversion. Grams to Cups uses named ingredient density conventions rather than an arbitrary user-entered density.

How do I convert kilograms back to ounces?

Swap units reverses the pair, or use ounces = kilograms / 0.028349523125. One kilogram displays as 35.2739619496 oz, and half a kilogram as 17.6369809748 oz. The shortcut kilograms ≈ ounces / 35 is about 0.782748% high compared with the exact factor. That difference is arithmetic, not a recommendation about a parcel or scale. Re-entering a rounded display uses the rounded quantity.

Why does it show grams, pounds and stone as well?

Because a weight is easier to judge beside the units you already use, and most converters make you pick one target before they tell you anything. Under the answer the same weight is listed in milligrams, grams, kilograms, tonnes, pounds, stone and US short tons, each with its own Copy button, and one switch in the readout adds the three rarer ones: long tons, carats and grains. For 1 oz that reads 28.349523125 g, 0.0625 lb and 0.00446428571429 st.

Is this the ounce that gold is priced in?

This page uses avoirdupois ounces. A source that explicitly specifies troy ounces uses exactly 31.1034768 g per troy ounce, about 9.7% more. The metal or product alone does not establish the convention, and Troy ounce is absent here. Convert a supplied troy-oz quantity separately to grams using that factor, then select Gram to convert the resulting mass.

Does anything I type leave my browser?

Your input and converted values are calculated in the browser and are not uploaded by the converter. The definitions arrive with the page, so conversion needs no external data lookup and keeps working offline after the page has loaded. The core conversion needs no account. This focused page opens on Ounce (oz) to Kilogram (kg), while preserving the main converter’s saved unit pair. When storage is usable, a saved value and uncommon-unit preference can travel between pages. Its suffix must still match From. Valid deliberate scalar edits can save those fields after a short delay; invalid or incomplete drafts preserve the saved record. Unusable or conflicting records remain until you use Forget saved settings, which keeps the current conversion on screen. Copy result copies the displayed headline without digit-grouping commas; each visible conversion row has its own Copy button. Displayed and copied values round to twelve significant digits. If native copying fails, a complete selectable summary identifies the input, selected pair and conventions and includes every unit in the category, including uncommon units.
