IRA (academic performance index): formula and example
The IRA, sometimes written as CR (coeficiente de rendimento) or CRA, is Brazil's answer to the US GPA: IRA = Σ(gradeᵢ · creditᵢ) / Σ creditᵢ, where the credits usually track the credit-hour load of each course. Most public universities (USP, UFRJ, UFMG) grade on a 0–10 scale, though some private schools borrow the 0–4 US style. Example: take Calculus at 6 credits × 8.0, Programming at 4 × 9.0 and Physics at 4 × 7.0 → (48 + 36 + 28) / 14 = 8.0. The CRA normally counts approved subjects only. The CRG (general) counts every enrollment, failures and re-takes included. Clearing 7.5 is the usual cutoff for academic honors.
Applications
ProUni and FIES check your IRA to keep a scholarship active. Study-abroad and exchange programs (Ciências sem Fronteiras-style, university-to-university) tend to ask for an IRA above 7.0 or 8.0. CAPES and CNPq research grants (PIBIC, IC, mestrado) rank applicants by IRA. Graduate-school admissions lean on it as a first screen, next to the entrance exam. And internal transfers between universities score candidates the same way.
FAQ
What is the difference between IRA, CR, CRA and CRG? Across institutions they mostly mean the same thing. The real split is CRA (cumulative, approved only) versus CRG (general, failures included), with IRA serving as the catch-all term.
Do failed subjects count? In the CRG and in most IRA formulas, yes. A grade below the passing line drags the average down and sticks in your record even after you re-take the course.
How do I convert a 0–10 IRA to a 0–4 GPA? As a back-of-the-envelope guess, GPA ≈ IRA × 0.4. For anything official, though, exchange offices publish their own conversion table and you're expected to use it.

Stand Density Index (Reineke)
Computes Reineke's stand density index, SDI = trees per hectare × (quadratic mean diameter ÷ 25)^1.605, which expresses the stocking of a forest stand as the equivalent number of trees per hectare it would hold if every one measured 25 cm DBH — the 10 inches of the original 1933 work, rounded in the metric version. The exponent 1.605 is the slope of the self-thinning line Reineke fitted empirically, and it is precisely what makes the index nearly independent of age and site quality, unlike a plain trees-per-hectare count. The number guides thinning decisions when compared with the species maximum SDI, which for most species falls between 1,000 and 1,200: competition mortality typically starts around 55% to 60% of the maximum, and the recommended management zone runs from 35% to 55%. In the example, 559 against a maximum of 1,100 gives about 51%, meaning the stand is still below the self-thinning threshold but already at the top of the management zone. Enter the number of trees per hectare and the quadratic mean diameter.
Cake Yield by Pan Size
Computes slices and dough grams yielded by round pans of various diameters.
Mass Recovery
Calculate the mass recovery (mass yield) of a mineral processing operation, R = (concentrate mass ÷ feed mass) × 100%, dividing the concentrate mass produced by the ore feed mass. The result, in %, is the fraction of mass reporting to the concentrate — different from metallurgical recovery (which measures the fraction of metal recovered). Low mass recovery is typical of lean ores (little concentrate from much feed); high indicates rich ore or poorly selective concentration. Combined with the grades, it closes the plant's mass balance. Enter the concentrate and feed masses.

Paper Breaking Length
Compute the breaking length (self-rupture) of paper, L = tensile index / 9.80665, in km — the length of a paper strip that, hung from one end, would break under its own weight. It is an intuitive, classic way to express tensile strength, independent of grammage. Common papers break around 3–8 km; high-strength papers, more. Enter the tensile index (N·m/g).
