Home > Physics > Heat Index Calculator

The heat index calculator estimates the heat index felt via the human body based totally at the environmental temperature and relative humidity. The calculator robotically converts the values from one scale to another.

What is the heat Index?

“the heat index is the temperature or the humidex(humidity index) of temperature felt through the human frame”

Whilst you are measuring the warmth index, you are thinking of each the temperature and the humidity degree of the encompassing surroundings.

A way to Calculate warmth Index?

You could degree the warmth index through calculating the environmental temperature, and relative humidity of the encircling. the heat index can also vary notably inside the shaded location and in daylight because of adjustments in temperature. The system for measuring the heat Index is:

HI = c₁ + c₂T + c₃φ + c₄Tφ + c₅T² + c₆φ² + c₇T²φ + c₈Tφ² + c₉T²φ²

Where:

  •  T = Temperature in °C or °F 
  •  φ = Relative Humidity as a %
  •  c = Constant Parameters dependent on the temperature

The Values of “c” in  °C and °F:

There may be exceptional values of the steady price “c” because of special temperatures. the warmth index humidity at once impacts the measurement of the heat index. You need to remember what is the temp regular “c” for a specific temperature(°C or °F), its values going to trade without problems for relative temperatures. try and pick out the warmth index chart for a selected temperature (°C or °F). you could degree what is the heat index these days with the warmth index calculator irrespective of location. The wet bulb effect might also boom at a higher warmth index. inside the table beneath the values of “c” in °C and °F are given:

PARAMETER °C  °F
c₁ -8,785 -42,379
c₂ 1,611 2,049
c₃ 2,339 10,143
c₄ -0,146 -0,225
c₅ -1,231 ⋅ 10⁻² -6,838 ⋅ 10⁻³
c₆ -1,642 ⋅ 10⁻² -5,482 ⋅ 10⁻²
c₇ 2,212 ⋅ 10⁻³ 1,229 ⋅ 10⁻³
c₈ 7,255 ⋅ 10⁻⁴ 8,528 ⋅ 10⁻⁴
c₉ -3,582 ⋅ 10⁻⁶ -1,990 ⋅ 10⁻⁶

Results of the warmth Index:

The warmth index could have doubtlessly extreme medical consequences on people. In excessive heat index situations, perspiration is hindered due to decreased evaporation because of high humidity. the heat index humidity may be tough to respire and cramping may additionally occur. higher to use the humidity calculator before visiting to a selected vicinity or vacation spot. There may be various consequences of the excessive heat index.

Heat Index Chart:

The following warmness index chart describes the precautionary measures at diverse temperatures.

Celsius Fahrenheit Precautions
27-32°C 80-90°F Fatigue is possible with prolonged exposure and activity. Continuing activity could result in heat cramps.
32-41°C 90-105°F Fatigue is possible with prolonged exposure and activity. Continuing activity could result in heat cramps.
27-32°C 80-90°F Extreme caution: heat cramps and heat exhaustion are possible. Continuing activity could result in heat stroke.
41-54°C 105-130°F Danger: heat cramps and heat exhaustion are likely; heat stroke is probable with continued activity.
Over 54°C Over 130°F Extreme danger: heat stroke is imminent.

The warmth index calculator shows the atmospheric conditions of a positive vicinity. the heat index chart may additionally suggest a hot, particularly warm, heat, and extraordinarily hot warmth index. in spite of the rising heat index humidity, the real feels like the temperature calculator can also indicate it's far bearing warmness index

How does Our Calculator work?

For an correct estimation of the warmth index, comply with the steps:

Input:

  • Pick the parameter from the list
  • Enter the relative parameters
  • Hit the calculate button

Output:

  • Warmness index temperature(Celsius, Fahrenheit, Kelvin)

The dew factor, temperature, or relative humidity are interconnected and interconvertible. the warmth index calculator will right away calculate their values.
