A pure volume-to-volume conversion between the US tablespoon and the metric milliliter, no density involved.
How it works
Multiplying tablespoons by 14.7868 mL gives milliliters; dividing milliliters by that same constant gives tablespoons back. Type into either field and the other updates instantly.
What this does not include
This does not include converting to a weight in grams — for that, use this site’s tbsp-to-grams calculator instead, which factors in an ingredient’s density.
How to use this calculator
- Enter a value in either tablespoons or milliliters — the other field fills in automatically.
Frequently asked questions
Why isn’t a tablespoon a round number of milliliters?
Because the US tablespoon comes from the US customary gallon system, not designed to align neatly with the separately defined metric milliliter.
Is a UK tablespoon the same size?
No — a UK/metric tablespoon is commonly 15 mL, slightly larger than the US tablespoon’s 14.79 mL used here.
Where is this conversion most often needed?
Recipe conversion between US-volume and metric-volume sources.
