pascal
- Definition: The pascal is a unit of pressure defined as one newton per square meter. It is the SI (International System of Units) derived unit of pressure.
- Symbol: The symbol for pascal is “Pa”.
- Usage: The pascal is commonly used to measure atmospheric pressure, stress, and mechanical pressure in various fields such as engineering and meteorology.
bar
- Definition: The bar is a metric unit of pressure, defined as 100,000 pascals. It is used to express pressure in a more convenient format compared to pascals in many practical applications.
- Symbol: The symbol for bar is “bar”.
- Usage: The bar is often used in meteorology, aviation, and various engineering applications, particularly in situations where pressures are in the range of atmospheric pressure.
Origin of the pascal
- The pascal is named after the French mathematician and physicist Blaise Pascal, who made significant contributions to fluid mechanics and pressure theory in the 17th century.
Origin of the bar
- The bar was introduced in the 19th century as a convenient unit for measuring pressure and is derived from the Greek word “baros,” meaning weight.
