How to Use the Calculator

  1. Enter the temperature in degrees Celsius (°C) in the input field.
  2. Click the "Calculate" button to compute the water vapor pressure.
  3. The water vapor pressure will be displayed in hPa.
  4. Click the "Reset" button to clear the input fields and results.

Working Principle

The water vapor pressure is the pressure exerted by water vapor in the air. It is an important parameter in meteorology and weather forecasting. The Magnus formula is used to calculate the water vapor pressure based on the temperature.

Formula Explanation

The formula used to calculate the water vapor pressure is:

P = 6.112 * exp((17.67 * T) / (T + 243.5))

Where:

  • P = Water Vapor Pressure (hPa)
  • T = Temperature (°C)
