What does mmHg mean in barometric pressure?
What does mmHg mean in barometric pressure?
Many barometers use mercury to measure barometric pressure. Since the chemical symbol for mercury is Hg, readings of barometric pressure are often reported in inches of mercury (in/Hg) or millimeters of mercury (mmHg). One atmosphere of barometric pressure is equal to 760 millimeters of mercury.
What is mmHg as a unit?
A millimetre of mercury is a manometric unit of pressure, formerly defined as the extra pressure generated by a column of mercury one millimetre high, and currently defined as exactly 133.322387415 pascals. It is denoted mmHg or mm Hg.
How do you read mmHg?
Blood pressure is measured in units of millimeters of mercury (mmHg). The readings are always given in pairs, with the upper (systolic) value first, followed by the lower (diastolic) value. diastolic blood pressure of 88 mmHg.
What is normal mmHg?
A healthy blood pressure reading should be lower than 120/80 mmHg. Normal blood pressure is less than 120 mmHg systolic and 80 mmHg diastolic (see blood pressure chart below), and may vary from 90/60 mmHg to 120/80 mmHg in a healthy young woman. A blood pressure of 140/90 mmHg or higher indicates high blood pressure.
Do I use kPa or mmHg?
KPa is widely used internationally as a unit of pressure and also measures eg the tyre pressure of cars. The unit mmHg (millimeter mercury column) is also used to measure blood pressure.
Why is mmHg?
As mercury is so much denser than water or blood, even very elevated blood pressures result in it rising no more than about a foot. This quirk of medical history gives us the modern measurement unit for blood pressure: millimetres of mercury (mmHg).
¿Cómo convertir 2 atmósferas a Mercurio?
Para transformar atmósferas a milímetros de mercurio, basta utilizar la fórmula de conversión a continuación: Valor en milímetros de mercurio = valor atmósferas x 759.9999 Suponga que tú desees convertir 2 atmósferas a milímetros de mercurio. En este caso, tú tendrás: Valor em milímetros de mercurio = 2 x 759.9999 = 1520 (milímetros de mercurio)
¿Qué equivale a 3 atmósferas?

¿Qué es una atmósfera estándar?
Nota: algunos valores pueden estar redondeados. La atmósfera estándar ( símbolo:atm) es una unidad de presión definida como 101325 Pa (1.01325 bar). La presión de 1 atm puede también ser expresada como: ≡ 760 torr≈ 760.001 mmHg, 0 °C, ssujeto a revisión. Necesitan más mediciones de la densidad de mercurio está disponible.
