About Ounce
The avoirdupois ounce is 1/16 of an avoirdupois pound (about 28.35 g). Cooking and postal weights often use ounces.
About Microgram
The microgram is one millionth of a gram. It appears in pharmacology and trace analysis.
How to convert ounces to micrograms
1 ounce is equal to 2.83495231e+7 microgram:
1 oz = (28.349523125 g ÷ 0.000001 g) ug = 2.83495231e+7 ug
Each ounce is defined as 28.349523125 g and each microgram as 0.000001 g, so one oz equals 28.349523125 ÷ 0.000001 ug = 2.83495231e+7 ug.
Let w(oz) be the numeric value of the same mass measured in Ounce (oz), and w(ug) the value in Microgram (ug). Then:
w(ug) = w(oz) × (28.349523125 / 0.000001)
Equivalently, divide by how many oz fit into one ug (grams per ug divided by grams per oz):
w(ug) = w(oz) ÷ 3.52739619e-8
Or: microgram = ounce ÷ 3.52739619e-8
Examples
Example #1: Convert 20 oz to microgram
20 oz = 20 oz × (28.349523125/0.000001) ug = 566990462.5 ug
20 oz = 20 oz ÷ 3.52739619e-8 = 566990462.5 ug
Example #2: Convert 50 oz to microgram
50 oz = 50 oz × (28.349523125/0.000001) ug = 1417476156.25 ug
50 oz = 50 oz ÷ 3.52739619e-8 = 1417476156.25 ug
Summary
To convert Ounce to Microgram, multiply the value in oz by the ratio of grams per oz divided by grams per ug. Equivalently: value_ug = value_oz × (28.349523125 / 0.000001). Numerically, 1 oz equals 28349523.125000004 ug.
Relationship context
You are converting between imperial / UK (stone, long ton, pound, ounce) (Ounces) and metric (SI) (Micrograms). Metric mass is decimal from the gram; US and imperial masses use pounds and ounces with fixed definitions relative to the kilogram. The numeric factor used here is 2.834952e+7.
