HumidCalc vs Dew Point & Humidity Calc

＊Weather data supported＊ A versatile humidity calculation app for everyone from general users to engineers — also suitable for agricultural applications. This app allows you to easily calculate indicators such as the Discomfort Index, WBGT (estimated heat stress index), Volumetric Absolute Humidity (an important indicator for influenza prevention), and Humidity Deficit (HD) used in agriculture, using weather data. You can also calculate a wide range of air properties from dry-bulb temperature (normal air temperature) and wet-bulb temperature obtained from ventilated psychrometers such as the Assmann psychrometer.
Atmospheric pressure can be entered manually. The app supports 12 indicators across 16 calculation items, and unit conversion between Celsius/Fahrenheit and SI/Imperial units can be performed instantly by switching the temperature unit setting. ■ High-Precision Calculation Engine This app uses the Wexler–Hyland equations combined with numerical analysis, enabling highly accurate and stable calculations across a wide range of environmental conditions. ■ Calculable Indicators * Wet Bulb Temperature * Dew Point Temperature * Frost point temperature * Relative Humidity * Humidity Ratio(Absolute Humidity) * Mass-based absolute humidity * High-resolution mass-based absolute humidity * Volumetric absolute humidity * Humidity Deficit (HD) * Vapor Pressure Deficit (VPD) * Enthalpy * Specific Volume * Saturation Vapor Pressure * Water Vapor Partial Pressure * Boiling Point of Water * WBGT (Estimated value) * Discomfort Index (DI) Supplementary Notes on WBGT & Discomfort Index Outdoor WBGT is defined as: WBGT = 0.7 Tnw + 0.1 Td + 0.2 Tg (°F) Since globe temperature (Tg) is not an input parameter, it is estimated from dry-bulb temperature (Td) using: Tg = 1.45 Td − 27.162 (°F) Td and Tg show a strong correlation (n = 17,376, R² = 0.919). Natural wet-bulb temperature (Tnw) is obtained by converting the measured wet-bulb temperature from an Assmann psychrometer to natural conditions, assuming a wind speed of 98.4 fpm (0.5 m/s) or less. Details of this conversion algorithm are omitted. The Discomfort Index (DI) is calculated as: DI = 0.4 × (Td + Tw) + 15 (°F). ■ Weather Data & Sensors By tapping the Weather Data button, you can obtain current atmospheric pressure, dry-bulb temperature, and wet-bulb temperature. On devices equipped with a barometric pressure sensor, pressing the MEAS button allows direct pressure measurement. Wet-bulb conditions can be set to Normal or Frozen (effective below freezing). Corrected values can also be displayed for non-ventilated psychrometers such as the August psychrometer (ventilated types recommended for accuracy). ■App Ecosystem Integration You can directly receive calculated dry-bulb and wet-bulb temperatures from the companion app “Calculator of Air”. (Please note that calculations must be performed in Calculator of Air before data can be transferred.) By combining HumidCalc with Calculator of Air, you can, for example, derive multiple air properties from known Enthalpy and Humidity Ratio values. ■Input Ranges * Dry-Bulb & Wet-Bulb Temperature: −22°F to 122°F (−30°C to 50°C) * Atmospheric Pressure: 17.72 inHg to 73.09 inHg (600 hPa to 2475 hPa) * Dew Point: −58°F to 122°F (−50°C to 50°C) * Relative Humidity: 0% to 100% (1% steps) ■Notes When using an August psychrometer, calculations assume an air velocity at the sensing element of 98.4 fpm (0.5 m/s) or less. As a result, calculated values may differ from those listed in humidity tables included with commercial August psychrometers. ■Disclaimer 1. Please use values within reasonable temperature ranges (approximately 32°F to 104°F / 0°C to 40°C). Extremely unusual inputs may produce inaccurate results. 2. While every effort has been made to ensure high precision, minor errors may occur due to floating-point limitations. 3.

Dew Point & Humidity Calc is the ultimate tool to find the exact temperature at which the water vapor of atmospheric air condenses into liquid water, reaching its coolest point called saturation. Using this premium calculator, you can accurately analyze air moisture, calculate dew points, and determine relative humidity instantly. Perfect for HVAC professionals, meteorologists, engineers, outdoors enthusiasts, and homeowners tracking indoor climate comfort, this app provides accurate calculations based on standard thermodynamic and psychrometric formulas. Our app offers two advanced calculators tailored to your needs: 1. DEW POINT CALCULATOR Calculate the exact dew point temperature using the Air Temperature and Relative Humidity (%). Understand when moisture will convert to liquid water and condensation will occur. 2. PSYCHROMETRIC CALCULATOR A powerful tool to calculate either Relative Humidity (RH) or Dew Point. Input the Dry Bulb temperature plus either the Wet Bulb temperature or the Dew Point temperature to instantly get full psychrometric details, including relative humidity and remaining wet/dry bulb values. TEMPERATURE UNIT CONVERTER We support Celsius (°C), Fahrenheit (°F), and Kelvin (K). The built-in unit converter allows you to seamlessly convert values between these temperature scales with a single tap. KEY FEATURES: - High-precision thermodynamic calculations (Magnus-Tetens & psychrometric formulas). - Clean, premium iOS-style interface built with an 8pt layout grid. - Full support for Light and Dark Modes, matching your system settings. - Universal unit conversions for all calculators. - Fully localized in 18 languages to support users worldwide. - No ads, clean typography, and fast computations.
