Both mean the same volume, but choosing the right form makes your writing clear, polished, and audience-friendly.

In the United States, liter is the accepted spelling. It appears in everything from science papers to soda bottles. American English typically simplifies many French-influenced words.

Academic writing often depends on the style guide you’re following. APA, MLA, and Chicago styles based in the U.S. prefer liter. UK-based academic formats stick to litre.

Always check the guide before submitting your work. If you’re unsure, use liter for U.S. journals and litre for British or European ones. Precision matters here.

In Multinational or General Contexts

When writing for a global audience, pick a standard and stay consistent. Many multinational companies use litre because it’s more internationally recognized outside the U.S.

You could also mention both spellings once, like liter (litre), and then choose one. This keeps communication clear without confusing your readers later on.

Etymology of “Litre” and “Liter”

The word litre comes from the French “litre,” which traces back to ancient measurement systems. French influence spread into English, bringing the term along.
