Kilopascals to Millimeters of Mercury Converter
1 kilopascal ≈ 7.50061505 millimeters of mercury
Almost identical to the torr, but defined separately. This uses conventional mmHg, not a temperature-specific mercury-column realization.
1 kilopascal equals 7.50062 millimeters of mercury
How to convert kilopascals to millimeters of mercury
Unit conversion preserves the pressure reference. Gauge pressure and absolute pressure are different readings; changing between them also needs the ambient pressure. Mercury and water-column units use the conventions stated in their unit notes.
mmHg = kPa × 7.50061505One kilopascal is 7.50061505 millimeters of mercury, so a single multiplication converts any value.
75.0062 mmHg ≈ 10 × 7.50061505Almost identical to the torr, but defined separately. This uses conventional mmHg, not a temperature-specific mercury-column realization.

Sources and precision
Table results are rounded to 8 significant digits; formula constants may be rounded to 10. Worked example answers use 6 significant digits. The converter starts at 6 significant digits and lets you change display precision. Calculations use the stored factors without intermediate rounding. Exact unit definitions do not make an input measurement more precise; conventional and measured factors follow the assumptions stated here.
