Cumulative hours to reach each CEFR level
The Common European Framework of Reference (CEFR) sorts language proficiency into six levels (A1, A2, B1, B2, C1, C2). Both the Cambridge English Profile and the Council of Europe put numbers on the cumulative guided learning hours each one demands: A1 ~80–100h; A2 adds ~180–200h; B1 adds ~350–400h; B2 adds ~500–600h; C1 adds ~700–800h; C2 adds ~1.000–1.200h. Treat those as a baseline for a Portuguese speaker tackling English. The FSI language categories shift the totals a lot. Category I, say Spanish, goes faster; Category IV, which covers Japanese, Arabic, Korean and Chinese, can run 2–3× longer. Immersion — studying abroad, working full days in the language — speeds things up by roughly 30–50%. As an example, moving from B1 to B2 in Category II usually means another 500–600 hours of focused study backed by productive practice.
Applications
Handy when you're mapping out Cambridge certifications (KET, PET, FCE, CAE, CPE), IELTS, TOEFL, DELE (Spanish), DELF/DALF (French), Goethe-Zertifikat (German), JLPT (Japanese), or an exchange program. Employers lean on CEFR when hiring (B2 is common for international roles, C1 for senior ones), and universities tend to ask for B2/C1 before admitting you to postgraduate study abroad.
FAQ
Are Duolingo hours equivalent? Only up to a point. Time in the app mainly drills recognition. Getting past B1 takes real listening, reading and conversation.
What is the FSI language category? The U.S. Foreign Service Institute ranks languages by how hard they are for native English speakers, from I (easiest) to IV (hardest). Apply the same logic to how far the target sits from Portuguese.
How is the level officially certified? You sit a standardized exam tied to the CEFR scale, such as Cambridge B2 First, C1 Advanced, IELTS bands, TOEFL iBT, or whatever the equivalent is for your language.
Can children reach C2 faster? They can, especially with early exposure and immersion. The hour figures above assume an adult following structured study.

Reservoir Emptying Time
Calculate the time to empty a constant-surface-area reservoir through a bottom orifice, t = 2·A_s·√H ÷ (C_d·A_o·√(2g)), from the water-surface area A_s (m²), the outlet orifice area A_o (m²), the initial head H (m, water height above the orifice) and the discharge coefficient C_d (≈ 0.6 for orifices). The formula integrates Torricelli's equation over the drawdown: as orifice flow drops while the level (and head) falls, emptying decelerates, and total time results from integrating dH/dt. It is useful for designing dam bottom outlets (used to lower the reservoir in emergencies or for maintenance), emptying industrial tanks and basins. Time grows with reservoir area and the square root of head, and falls with orifice area — emptying large reservoirs takes a long time, a real limitation in dam emergency management. It assumes constant A_s; real reservoirs vary with elevation. Enter the surface area, orifice area, initial head and discharge coefficient.
