Converting from Foot of Mercury (ftHg) to Newton per Square Millimeter (N/mm²) in Pressure

What is Foot of Mercury (ftHg)

Foot of Mercury (ftHg) is a unit of pressure that represents the pressure exerted by a column of mercury one foot in height at 0°C. It is commonly used in meteorology and aviation to measure barometric pressure.

What is Newton per Square Millimeter (N/mm²)

Newton per Square Millimeter (N/mm²) is a unit of pressure in the International System of Units (SI). It is a metric unit that represents the amount of force applied per unit area of a surface.
