- **Keywords:** mmhg, mercury, kpa, kilopascal, pressure, conversion

## Overview

Enter millimeters of mercury and convert with 1 mmHg = 0.1333223684 kPa.

## Inputs

- **Millimeters of Mercury** (number): e.g. 760
- **Decimal Precision** (number)

## When to use

- When translating clinical blood pressure readings from mmHg to SI units (kPa) for medical research papers.
- When calibrating laboratory pressure gauges or barometers that output measurements in millimeters of mercury.
- When verifying meteorological or vacuum engineering pressure specifications that require kilopascal units.

## How it works

- Enter the pressure value in millimeters of mercury (mmHg) into the input field.
- Specify the desired decimal precision (up to 10 decimal places) to control the rounding of the output.
- Click convert to calculate the equivalent pressure in kilopascals (kPa) using the exact ratio of 0.1333223684 kPa per mmHg.

## Use cases

- Converting physiological blood pressure measurements (like 120/80 mmHg) to kilopascals for academic publications.
- Standardizing vacuum chamber pressure readings from mmHg to kPa for industrial manufacturing logs.
- Translating barometric weather data from mercury-based units to metric kilopascals.
