1) What is the exact relationship between kPa and mmHg?
By definition at standard conditions, 101.325 kilopascals equals 760 millimeters of mercury. Therefore 1 kPa = 760/101.325 ≈ 7.500616827 mmHg.
2) Does temperature affect the conversion?
The numerical factor shown uses the conventional standard atmosphere definition. For most engineering and clinical uses this constant is sufficient; temperature effects are embedded in the original definition of mmHg.
3) Can I convert in both directions?
Yes. Choose the direction from the dropdown to convert kPa → mmHg or mmHg → kPa. Results update instantly.
4) What do significant figures control?
Significant figures set the precision of the displayed output while retaining scientific rounding rules. Calculations use full double precision internally.
5) How do I share a result?
Use the “Permalink” button. The link includes your inputs and precision so colleagues can open the exact same calculation.
6) Why do my pasted numbers with commas get rejected?
The input accepts plain numbers. Thousands separators and spaces are automatically stripped, but other locale characters may need manual cleanup.
7) Is this suitable for clinical documentation?
The factor is the accepted standard. Always follow your institution’s policies and round as required in charts and reports.
