How Many Grams in Half Ounce? Complete Conversion
How Many Grams in Half an Ounce?
14.1748 grams. That's your answer. Half an ounce equals exactly 14.1748 grams, though most people round it to 14.17g or even 14.2g for practical purposes.
Simple, right? But knowing the number is only half the battle. Here's everything else you actually need to know.
Why This Conversion Matters
Grams and ounces don't play nice together. The US uses ounces for weight, while most of the world uses grams. This creates constant headaches in:
- Cooking and baking — recipes come from everywhere now
- Weighing portions — especially in regions where cannabis is legal
- Shipping packages — international weight limits are in grams
- Nutrition tracking — food labels switch between systems
If you're working across systems, you need to know this conversion cold.
The Quick Math
One ounce = 28.3495 grams
Half an ounce = 28.3495 ÷ 2 = 14.1748 grams
That's it. Divide the full ounce value by two.

How to Convert Any Ounce Amount to Grams
Here's the formula you need:
Grams = Ounces × 28.3495
Examples
- 1 oz → 1 × 28.3495 = 28.35g
- 0.5 oz → 0.5 × 28.3495 = 14.17g
- 3 oz → 3 × 28.3495 = 85.05g
- 10 oz → 10 × 28.3495 = 283.50g
Use a calculator if precision matters. For cooking, rounding to 28.35g per ounce works fine.
Common Situations Where This Matters
In the Kitchen
Many international recipes list ingredients in grams. If you're in the US and a recipe calls for "100g flour" and you only have ounce measuring cups, you need to know that 100g is roughly 3.53 ounces.
Going the other way: if a recipe says "4 oz chocolate," that's about 113.4 grams.
Weighing Cannabis
Legal markets sell in grams and ounces. A half-ounce is a standard purchase size. At 14.17 grams, you know exactly what you're getting.
- 1 gram = roughly 1-2 joints
- 3.5 grams (⅛ oz) = small bag/2-3 joints
- 7 grams (¼ oz) = moderate amount
- 14 grams (½ oz) = standard purchase
- 28 grams (1 oz) = heavy use/month supply
Shipping and Postal Limits
Many countries have strict weight limits for packages. If you're shipping internationally, knowing gram equivalents keeps you from overpaying or getting hit with customs fees.
Getting Started: Measure Accurately
You need a digital scale. Kitchen measuring cups don't cut it for precise gram weights. Here's how to do it right:
- Get a digital scale — $10-20 on Amazon. Look for one that measures in 0.01g increments if you need precision.
- Calibrate if needed — some scales need a calibration weight.
- Place your item on the scale — make sure it's clean and dry.
- Read the display — wait for it to stabilize.
- Convert if needed — use the formula above.
Don't have a scale? Use approximate conversions and accept the margin of error. For cooking, this usually doesn't matter much. For cannabis, you need precision.
The Bottom Line
Half an ounce = 14.1748 grams.
Remember: 1 oz = 28.3495g. Cut it in half. That's your conversion.
