A kilopound per square inch (ksi) is a unit of pressure and stress used in the Imperial and US customary systems of measurement.
It represents a force of one thousand pounds-force applied to an area of one square inch.
A kilopound per square inch (ksi) is a scaled unit directly related to the more common pound per square inch (psi). The prefix "kilo-" signifies one thousand.

The conversion to megapascals (MPa) is essential for converting measurements to the SI (metric) system.
In materials science and structural engineering, ksi is a primary unit for quantifying the mechanical properties and material strength of a substance.
It is commonly used to express:
For example, the strength of high-performance materials like structural steel and aluminum alloys is frequently specified in ksi.
This provides engineers with the critical data needed for safe and reliable design.
While the metric system's megapascal (MPa) is the international standard, ksi remains prevalent in American engineering, particularly in the aerospace, automotive, and construction industries.
An inch of mercury, often abbreviated as inHg, is a unit of pressure.
It is not part of the standard metric (SI) system but is widely used in the United States and in specific fields like meteorology and aviation.
The unit is defined by its name: it is the amount of pressure exerted by a column of liquid mercury exactly one inch tall at a standard temperature.
You will most commonly encounter inches of mercury in a few key areas:
Weather Reporting: In the U.S., inHg is the standard unit for reporting barometric pressure (also known as atmospheric pressure).
A "high" pressure system indicating clear weather might be around 30.50 inHg, while a "low" pressure system associated with storms could be 28.50 inHg.
Aviation: This measurement is critical for pilot safety.
Pilots use the local barometric pressure (in inHg) to calibrate their altimeters—instruments that measure altitude—to ensure they are flying at the correct height.
Vacuum Systems: The unit is also widely used in science and industry to measure vacuum pressure.
This is common in systems like air conditioning, refrigeration, and for monitoring the manifold pressure in piston engines.
Because inHg is not a global standard, it's often necessary to convert it to other pressure units for calculations or international use.
