Saybolt Seconds Universal/ Saybolt Universal Seconds (SSU/SUS)

The most common viscosity measurement prior to the international acceptance of centiStokes (cSt). SUS measures are now obsolete. To convert measurements from SUS at 100°F to an approximate value in cSt at 40°C (ISO viscosity grade), divide the SUS value by 5.
