Welcome to the Viscosity/Temperature conversion app developed by Saybolt.

This App is a handy Viscosity/Temperature conversion calculator for petroleum fuels. The calculator converts the Kinematic Viscosity in Centistokes (cSt) at a reference Temperature in Fahrenheit or Celcius to the desired target value.

The App changes into a traditional Viscosity/Temperature slider when the mobile device is held in landscape position. By reading the slider scale under the hairline Kinematic Viscosity units can be compared, such as the Saybolt Universal Seconds or Saybolt Seconds Furol, with the nowadays more widely used Centistokes. Temperature and viscosity conversions with the slider are indicative.
