PetroCalc – the trusted petroleum calculator in your pocket
PetroCalc is the all‑in‑one oil & gas calculator that engineers, technicians and students can rely on for fast, accurate viscosity calculations, crude‑oil blending and every other petroleum‑property task. Whether you need an oil calculator for the field, a crude‑oil calculator for the lab or a classroom reference, PetroCalc streamlines every petroleum calculation—from viscosity blending to heating‑value look up—completely offline.
KEY FEATURES
• Unit Conversion – Instantly switch between energy units (MJ/m³, MBTU/bbl, BTU/gal, kCal), temperature (°F/°C), pressure (psi/bar), oil‑density & gravity (kg/m³, API °, specific gravity), kinematic ↔ dynamic viscosity (cSt ↔ cP) and operational scales (SUS, SFS, Redwood I, Engler °), plus calorific‑value conversions and more with our intuitive oil & gas calculator interface.
• Distillation‑Curve Tools – Convert temperatures between TBP, ASTM D86, D1160 and D2887 scales and perform yield‑temperature interpolation for full distillation‑curve analysis.
• Blending Tools – Execute precise crude‑oil blending and petroleum blending for RVP, Flash Point, Smoke Point, Pour/Cloud/Freeze Point, API Gravity, Aniline Point, Mercaptan Sulfur, Nitrogen and custom fractions.
• Fuel Property Indices – Compute Cetane Index (ASTM D4737 A/B, D976), Driveability Index, Refractive Index and additional viscosity calculations.
• Heating Values – Get Gross & Net HHV in MJ/m³, MBTU/bbl, BTU/gal, kCal/kg, etc.
• Boiling‑Point Utilities – Five average‑BP methods (Volume, Weight, Molal, Cubic, Mean).
• K‑Factor Calculations – UOP K, Watson K, VRC K, Whole‑Crude K at any temperature.
• Viscosity Prediction – Single‑point, two‑point (Twu) and API 11A4.2 models with built‑in viscosity blending conversions.
WHY PETROCALC?
• Developed by Haverly Systems, a leader in petroleum process modelling.
• Optimised for petroleum, chemical and process engineers—and perfect for students in engineering courses who need a dependable petroleum calculator and oil calculator for coursework.
• Works fully offline—no data connection required on‑site.
• Simple, accurate and fast: the only crude‑oil calculator and petroleum blending tool you’ll ever need.
Download PetroCalc today and tackle every oil & gas calculation—from distillation‑curve conversions and viscosity blending to heating values—with confidence.
