  • The EF English Proficiency Index (EF EPI) attempts to rank countries by the equity of English language skills amongst those adults who took the EF test. It is the product of EF Education First, an international education company, and draws its conclusions from data collected via English tests available for free over the internet. The index is an online survey first published in 2011based on test data from 1.7 million test takers. The most recent edition was released in November 2023.

  • You’re right, yet there are two definitions of the horse power, the imperial 1 hp ≈ 745.7 W and the metric 1 hp = 735.49875 W. The latter is usually given in its local name, e.g. as PS, cv, … etc., while the imperial is usually hp independent of the language of the document.

    As you said, in Europe, quantifying the power of a machine (e.g. a car) in horse powers is supplementary only and thus, does not suffice on its own, the data must always be given in kW.
