Your pocket-sized petroleum property calculator! PetroCalc is the all‑in‑one oil & gas calculator that engineers, technicians, and students 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‑ups—completely offline.
Trusted Petroleum Calculator in your Pocket!
The premier precision petroleum‑property calculator—convert units, blend crude oils, and predict viscosity & distillation values offline in the field, lab, or classroom.
Perform Unit Conversions
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.
Robust Petroleum Calculations
Compute Cetane Index (ASTM D4737 A/B, D976), Boiling‑Point Utilities, K‑Factor Calculations, and perform Viscosity Predictions.
Simple, Accurate, and Fast
The Only Crude‑Oil Calculator You’ll Need
Download PetroCalc today and tackle every oil & gas calculation—from distillation‑curve conversions and viscosity blending to heating values—with confidence.
