Know the limits. Ounces are mass, not fluid ounces or precious-metal troy ounces. “t” means metric tonne, not US short ton.

The model uses 0.45359237 kg per pound and 16 avoirdupois ounces per pound. A metric tonne is 1,000 kg.

Result = input × kilograms per source unit ÷ kilograms per destination unit

A few useful details

Can I convert mL into grams here?

No. Volume-to-mass conversion needs the specific material’s density.

What does lb mean?

It is the pound mass unit used in this converter.

Do I need an account?

No. This release runs without an account, API key or payment. Saving a favorite stores only the tool’s identifier in this browser, not your inputs.
