Heat Index Calculator

Heat Index?

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

When you are measuring the heat index, you are taking into account both the temperature and the humidity level of the surrounding environment.

The way to Calculate warmth Index?

you may degree the heat index via calculating the environmental temperature, and relative humidity of the surrounding. the heat index may vary considerably within the shaded region and in daylight because of adjustments in temperature. The formula for measuring the warmth Index is:

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

wherein:

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

The Values of “c” in °C and °F:

There can be unique values of the regular value “c” because of one of a kind temperatures. the heat index humidity directly impacts the size of the warmth index. You must bear in mind what's the temp consistent “c” for a particular temperature(°C or °F), its values going to trade effectively for relative temperatures. try to pick the warmth index chart for a particular temperature (°C or °F). you may degree what's the warmth index today with the heat index calculator irrespective of area. The wet bulb impact might also increase at a better heat index. inside the table underneath 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

Effects of the heat Index:

the heat index can have potentially extreme scientific results on human beings. In high warmness index situations, perspiration is hindered because of reduced evaporation as a result of excessive humidity. the heat index humidity may be hard to breathe and cramping can also show up. higher to use the humidity calculator before journeying to a particular area or destination. There may be diverse consequences of the excessive heat index.

Warmness Index Chart:

The subsequent warmness index chart describes the precautionary measures at various 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 situations of a sure place. the warmth index chart may also suggest a warm, particularly warm, warm, and extraordinarily warm warmness index. notwithstanding the growing heat index humidity, the actual feels just like the temperature calculator may additionally indicate it's miles bearing heat index

How does Our Calculator work?

For an accurate estimation of the heat index, observe the stairs:

Enter:

  • pick the parameter from the listing
  • input the relative parameters
  • Hit the calculate button

Output:

  • heat index temperature(Celsius, Fahrenheit, Kelvin)

The dew point, temperature, or relative humidity are interconnected and interconvertible. the heat index calculator will straight away calculate their values.
