In plain language

Actually translating and adapting it for a country.

Example

Translating strings, switching date formats and mirroring the layout for right-to-left languages.

Commonly confused with

Close neighbours that get substituted for each other. The difference is stated first, then the condition that picks one over the other.

vs.

Internationalization (i18n)

Term

Building so that language, direction, format and content can vary without code changes.

Key difference

Internationalisation is the engineering that makes translation and adaptation possible. Localisation is the work of adapting for one locale. You cannot localise a product that was never internationalised.

Use Localisation (l10n) when

  • A locale has been chosen and content is being produced.
  • The question is wording, imagery, currency or legal detail.
  • The engineering groundwork is already in place.

Use Internationalization (i18n) when

  • You are designing layouts, dates, numbers or string handling.
  • The question is whether the system can accommodate another locale.
  • Nothing has been translated yet.
