Interactive Conversion Programs and Calculators

Here are a few practical calculators and converters where you can use real numbers to get the values needed.

• Calculate the Viscosity index of an oil when you know the viscosities at 40 ℃ and 100℃
• Calculate the oil viscosity at 100℃ when you only know the ISO viscosity (viscosity at 40℃) and the viscosity index.
• Calculate the actual viscosity in your equipment at operating temperature
• Calculate the viscosity of a mixture of two oils (note: you should only mix oils of the same brand and type)
• Calculate the percentage each of two oils needed to mix and obtain a given end viscosity
• Convert between Degrees API, specific gravity, kilos per liter or pounds per gallon
• Calculate the CFM needs of your engine
• Convert between English and Metric measuring systems, as well as fuel consumption and conversion of viscosity systems between cSt, SUS, Redwood y Engler.
• Graph the basic viscosity curves of any 4 oils from their data sheets or their data sheets and the calculators above when the sheets are incomplete.
