Convert Attopascal to Newton/Square Millimeter
Attopascal
An attopascal (aPa) is a unit of pressure in the International System of Units (SI), equal to 10⁻¹⁸ pascals (Pa). A pascal is defined as one newton per square meter (N/m²). The attopascal is used in various scientific and engineering contexts.
The term "attopascal" combines the SI prefix "atto-", representing 10⁻¹⁸, and the unit "pascal," named after Blaise Pascal, a French mathematician and physicist known for his contributions to the study of pressure and fluid mechanics. The prefix "atto-" comes from the Danish word "atten," meaning "eighteen." The attopascal is used in contexts where pressures are extremely low.
Newton/Square Millimeter
The newton per square millimeter (N/mm²) is a unit of pressure in the International System of Units (SI). It quantifies force per unit area and is commonly used to measure pressure, stress, and tensile strength. Mathematically: 1 N/mm² = 1,000,000 N/m² = 1,000,000 Pa.
The unit is named after Sir Isaac Newton (1643–1727), an English mathematician, physicist, and astronomer who made significant contributions to classical mechanics and the study of forces. The newton as a unit was officially adopted in 1948 by the General Conference on Weights and Measures (CGPM) as part of the International System of Units (SI).
