atmosphere
- Definition: The atmosphere is a unit of pressure defined as 101,325 pascals, which is approximately equal to the average atmospheric pressure at sea level on Earth.
- Symbol: The symbol for atmosphere is ‘atm’.
- Usage: The atmosphere is commonly used in meteorology, aviation, and various scientific disciplines to express pressure.
pascal
- Definition: The pascal is the SI unit of pressure, defined as one newton per square meter. It quantifies internal pressure, stress, Young’s modulus, and ultimate tensile strength.
- Symbol: The symbol for pascal is ‘Pa’.
- Usage: Pascals are widely used in scientific and engineering contexts to measure pressure, stress, and tension in materials.
Origin of the atmosphere
- The atmosphere unit was formally defined in the late 19th century, derived from observations of atmospheric pressure and established to facilitate communication in scientific and engineering fields.
Origin of the pascal
- The pascal is named after Blaise Pascal, a French mathematician, physicist, and inventor who made significant contributions to fluid mechanics and pressure measurement in the 17th century.
