Convert Attopascal to Millimeter Water (4°C)
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.
Millimeter Water (4°C)
A millimeter of water (mmH₂O) is a unit of pressure based on the pressure exerted by a column of water 1 mm high at 4°C under standard gravity. It is commonly used in medicine and engineering.
The millimeter of water is derived from the pressure exerted by a 1 mm column of water at 4°C under standard gravity. It is used in contexts where pressures are relatively low.
