If the systolic blood pressure is 120mmHg, what is the pressure in lb/in^2 and in pascals?
To convert the systolic blood pressure from millimeters of mercury (mmHg) to pounds per square inch (lb/in^2) and pascals (Pa), we need to use conversion factors.
1. Converting to pounds per square inch (lb/in^2):
- We know that 1 lb/in^2 is equal to 0.4911 kilopascals (kPa).
- 1 mmHg is equal to 0.01933 lb/in^2.
- So, to convert mmHg to lb/in^2, multiply the mmHg value by 0.01933.
Calculating the conversion:
120 mmHg × 0.01933 lb/in^2/mmHg = 2.3196 lb/in^2
Therefore, the systolic blood pressure of 120 mmHg is approximately 2.3196 lb/in^2.
2. Converting to pascals (Pa):
- We know that 1 lb/in^2 is equal to 6894.76 pascals (Pa).
- To convert lb/in^2 to pascals, multiply the lb/in^2 value by 6894.76.
Calculating the conversion:
2.3196 lb/in^2 × 6894.76 Pa/lb/in^2 = 15984.9 Pa
Therefore, the systolic blood pressure of 120 mmHg is approximately 15,984.9 Pa.
