1 Ounce (oz) = 28,349.52 Milligrams (mg)
Ounces (oz) are part of the imperial system, often used in cooking and trade.
Milligrams (mg) are part of the metric system, commonly used for medicine, chemistry, and precise measurements.
To convert ounces to milligrams, use this formula:
Milligrams (mg) = Ounces (oz) × 28,349.52
Example: Convert 2 oz to milligrams:
2 × 28,349.52 = 56,699.04 mg
