Tips & Best Practices
-
Use this tool when converting between nearly equivalent low-pressure units for clarity in reporting
-
Consider the 0°C temperature assumption when working with millimeter mercury to maintain consistency
-
Be cautious when high precision is required due to slight differences in unit definitions
-
Verify outputs in calibration or sensitive instrumentation scenarios
Limitations
-
Slight measurement differences can occur due to exact unit definitions and temperature considerations
-
Not recommended for contexts requiring extreme accuracy without further calibration
-
Temperature assumptions (0°C for mmHg) may impact precision in some applications
Frequently Asked Questions
-
Why convert from torr to millimeter mercury (0°C)?
-
Both units measure low pressures and vacua with almost the same values, so converting facilitates reporting and measurement in different settings like clinical or laboratory environments.
-
Is the conversion between torr and mmHg exact?
-
The units are nearly equivalent with a very small difference in values due to their precise definitions, but they are not exactly the same.
-
Can I use this conversion for blood pressure readings?
-
Yes, millimeter mercury (0°C) is commonly used in clinical blood pressure monitoring and converting from torr can assist in this context.
Key Terminology
-
Torr [Torr]
-
A pressure unit equal to 1/760 of a standard atmosphere, used for measuring low pressures and vacua.
-
Millimeter mercury (0°C)
-
A pressure unit defined by the pressure exerted by a 1 mm column of mercury at 0°C under standard gravity.
-
Vacuum
-
A condition where pressure is significantly lower than atmospheric pressure, often measured in torr or mmHg.
