Optimal blood pressure is a reading of lower than 120/80. When your blood pressure numbers are consistently greater than 135/85, you're considered to have high blood pressure, or hypertension (but if you have diabetes or kidney disease, 130/80 is considered a high reading).

How can I check my blood pressure without a machine?

Place your index and middle finger of your hand on the inner wrist of the other arm, just below the base of the thumb. You should feel a tapping or pulsing against your fingers. Count the number of taps you feel in 10 seconds. Multiply that number by 6 to find out your heart-rate for one minute.

mmH2O to mmHg Conversion Table

1. 1 mmHg = 133.322 pascals (Pa)
2. 1 mmH₂O = 9.80665 pascals (Pa)
3. mmHg value x 133.322 Pa = mmH₂O value x 9.80665 Pa.

What unit is volume?

Volume is the measure of the 3-dimensional space occupied by matter, or enclosed by a surface, measured in cubic units. The SI unit of volume is the cubic meter (m³), which is a derived unit. Liter (L) is a special name for the cubic decimeter (dm³).

What is meant by real gas?

Real gases are nonideal gases whose molecules occupy space and have interactions; consequently, they do not adhere to the ideal gas law.
