About NIR8 Calculators – Free Online Pharmaceutical Calculator
NIR8 Calculators is a free online tool designed for pharmaceutical dispensing and batch calculation. Use it online directly in your browser — no download or installation needed.
The Formula Calculator supports three assay-based formulas: F1 (quantity required with assay and water correction), F2 (actual content calculation), and F3 (equivalent to F1 for alternate workflows). Enter the quantity (Q), water content (W %), and assay content (A %) to get instant, step-by-step printable results.
The (A+C)−B Calculator tracks standard quantities across up to four lots, calculates dispensed vs remaining quantities, and flags mismatches — ideal for multi-lot pharmaceutical batch dispensing.
All calculations use high-precision arithmetic and display full working steps with rendered equations. Results can be printed as formatted A4 landscape sheets for batch records.
