Convert Ounces to Ounces

To convert ounces to ounces (oz to oz), you don’t change the number. It’s the same unit, so the value stays the same.

• Rule: 1 oz = 1 oz
• Formula: ounces = ounces
• Example: 12 oz = 12 oz
• Example: 0.5 oz = 0.5 oz

Make sure you’re using the same kind of ounce:

• Weight ounces (oz) measure mass.
• Fluid ounces (fl oz) measure volume.

An oz to oz conversion only works as a direct match when both sides use the same unit type (oz to oz, or fl oz to fl oz).
