Square Foot per Hour

ft²/h

Definition

The square foot per hour is an imperial unit of kinematic viscosity, representing the ratio of dynamic viscosity to density over a time period of one hour. It is used for measuring very low kinematic viscosities in imperial units.

History/Origin

This unit was created by applying the hour time unit to the square foot per second, providing a more convenient scale for measuring very low kinematic viscosities in imperial unit systems.

Current Use

Used in specialized applications where very low kinematic viscosities need to be expressed in imperial units over hourly time periods, particularly in certain industrial processes and scientific measurements.

Square Millimeter per Second

mm²/s

Definition

The square millimeter per second is a unit of kinematic viscosity, representing the ratio of dynamic viscosity to density over a very small area. It is used for measuring low kinematic viscosities and provides a convenient scale for many practical applications.

History/Origin

This unit was created by applying the millimeter length unit to the square meter per second, providing a more convenient scale for measuring low kinematic viscosities in engineering and scientific applications.

Current Use

Commonly used in engineering and scientific applications where the square meter per second would be too large a unit. It is particularly useful for measuring the kinematic viscosity of oils, lubricants, and other fluids.
