Milligram

A milligram is a metric mass unit equal to one thousandth of a gram.

Milligrams are common in medicine, nutrition, chemistry, lab work, and small-dose measurements.

Ounce

An ounce is a mass unit equal to one sixteenth of a pound.

Ounces are common in US food packaging, recipes, parcels, postal weights, and smaller product specifications.

How to Convert Milligram to Ounce

Mathematically, ounce (oz) = milligram (mg) multiplied by the conversion factor shown below.

1 mg = 0.000035 oz

1 oz = 28,349.523125 mg

1 mg x 0.000035 = 0.000035 oz

The mass in ounce (oz) is the mass in milligram (mg) multiplied by 0.000035.

mass(oz) = mass(mg) x 0.000035

Or:

oz = mg x 0.000035

Formula: value × 0.0000352739619496

Example: 15 mg = 0.000529 oz

Example #1

Convert 500 milligram to ounce:

500 mg x 0.000035 = 0.017637 oz

Example #2

Convert 2,500 milligram to ounce:

2,500 mg x 0.000035 = 0.088185 oz

  1. Start with the mass in milligrams (mg).
  2. Multiply by 0.00003527396195 to convert milligrams into ounces.
  3. Use ounces when the result needs a small US customary mass unit rather than pounds.

Precision note: Use 0.00003527396195 ounces per milligram. Keep weight ounces separate from fluid ounces in labels and recipes.
