About Us

Learn about the 0z to Litres volume conversion tool, our mission, and the precision values we use.

What We Do

0zToLitres is a free online volume conversion tool. We convert fluid ounces (US) to litres using the precise conversion factor: 1 fl oz = 0.0295735295625 L. The result updates as you type — no forms, no page reloads, no accounts.

We built this because most conversion sites are cluttered with ads and slow to load. Our goal is a single-purpose tool that does one thing well: convert between fluid ounces and litres quickly and accurately.

The Numbers We Use

Our conversion factor comes from the legal definition of the US fluid ounce (1/128 of a US gallon) and the international definition of the litre (1 cubic decimetre). The exact value is 0.0295735295625 litres per US fluid ounce.

We default to US fluid ounces, which is the standard most people search for. Imperial (UK) fluid ounces are about 4% smaller (1 UK fl oz = 28.4131 mL vs. 29.5735 mL for US).
