Slugs to Ounces (slug to oz)
1 slug equals 514.7847769 ounces (rounded).
How to convert slugs to ounces
To convert slugs to ounces, multiply the number of slugs by 514.7847769. The factor is rounded to 10 significant digits. To go the other way, multiply ounces by 0.001942559386 (rounded).
ounces = slugs × 514.7847769
Example: 10 slugs = 5,147.847769 ounces.
About these units
Slug (slug)
About 14.594 kg. The US engineering unit of mass: the mass that accelerates at 1 ft/s² under a force of 1 pound-force.
Physics teachers in feet-and-pounds countries face an awkward fact: the pound is used both as a unit of mass and as a unit of force. The slug removes the ambiguity. It is the mass that a force of one pound-force accelerates at one foot per second squared, so that one slug equals one lbf s squared per foot. The British physicist Arthur Mason Worthington is credited with coining the name before 1900, taking it in the sense of a block of metal rather than the mollusc. An older name for it was the geepound.
One slug is about 14.594 kg, which is roughly 32.17 avoirdupois pounds, and the figure used here follows standard gravity, the international foot and the avoirdupois pound. An object of one slug weighs about 143.1 newtons at the Earth's surface. The unit belongs to the gravitational foot-pound-second system and stayed mostly in American engineering while a 1928 textbook noted that no special name was really needed. Its inch-based cousin, 12 slugs, is jokingly called a blob or slinch.
1 slug = 14.59390294 kilograms (approximately).

Ounce (oz)
One sixteenth of a pound, exactly 28.349523125 g. Used for food, mail and consumer goods in the US and UK.
A twelfth part is what ounce originally meant. It comes from the Roman uncia, one twelfth of the Roman pound, a word that also gave English the inch. The abbreviation oz does not come from English at all but from the Italian onza or oncia. Over the centuries many regions and trades used different ounces: the English Tower ounce of 29.16 g was abolished by Henry VIII in 1527, and the Dutch ons was redefined as exactly 100 g in 1820.
The avoirdupois ounce used for everyday goods is one sixteenth of a pound, exactly 28.349523125 g or 437.5 grains, the standard in the US and under the UK imperial system. It is not the same as the troy ounce for precious metals, and neither is the fluid ounce, which measures volume. Ounces still describe portions such as steaks and burgers, and they show up in unexpected places: fabric is graded by weight per area, so a 16 oz denim is a heavy cloth, and the copper on a circuit board is specified in ounces, where 1 oz is roughly 34.7 micrometres thick.
1 ounce = 0.02834952313 kilograms (approximately).
