The Conversion That Surprised Everyone

Most people guess 12 or 16 teaspoons for an ounce, but drying out common assumptions:

Final Thoughts

  • 1 US fluid ounce = 16 U.S. teaspoons (U.S. customary system)
  • 1 US fluid ounce ≈ 29.57 milliliters
  • 1 teaspoon ≈ 5 milliliters
  • So: 16 tsp × 5 ml = 80 ml ≈ 29.57 ml per US ounce? Wait—this is where confusion arises!
    Actually, 16 US tsp × 5 ml = 80 ml, but 1 US fl oz = 29.573 ml—meaning it takes closer to 17.6 US teaspoons to equal one fluid ounce.

To simplify:
≈16.3 U.S. teaspoons per US ounce (often rounded to 16 for conversions)

This small range—between 16 and 17 tsp per ounce—is critical in precise work. Use 16 tsp as your go-to, but remember the full context for accuracy.
