Ngendi kalkulator iki
The heat index, or apparent temperature, is how hot it really feels when humidity is combined with the air temperature, and this heat index calculator computes it from those two inputs. The body cools itself by evaporating sweat, but humid air is already close to saturated so sweat evaporates slowly, the cooling falters, and it feels hotter than the thermometer says. The tool uses the U.S. National Weather Service Rothfusz regression, a multi-term fit of temperature and relative humidity, together with its standard low- and high-humidity corrections.
As a worked example, 90 °F air at 60% relative humidity carries a heat index of about 100 °F — ten degrees hotter than the reading — and pushing the humidity to 80% drives it past 110 °F. The calculator returns the feels-like temperature, how much hotter that is than the air, and a humidity table so you can see how quickly the danger rises as the air grows muggier at a fixed temperature.
The regression is most accurate around 80 °F (27 °C) and above with meaningful humidity; below about 80 °F it reports no heat stress because humidity has little effect on comfort in cool air. It also grades the reading into the NWS danger bands — caution, extreme caution, danger and extreme danger — so a heat index above 103 °F signals a real risk of heat cramps or exhaustion, and above 125 °F a high risk of heat stroke, which is vital for planning outdoor work, sport and travel in hot weather.

Apa iku indeks panas?
Indeks panas, utawa suhu nyata, ya iku kacepetan panas kang dirasakaké nalika kelembapan relatif digabung karo suhu udara. Kelembapan dhuwur nglewati evaporasi banyu, mula awak ora gampang ngasilaké panas lan rasané luwih panas tinimbang sing dibaca thermometer.
Apa formulane?
Regresi NWS Rothfuss: HI = −42.379 + 2.04901523T + 10.14333127R − 0.22475541TR − … (kaliyan T ing °F lan R ing %), kaliyan panyesuaian kanggé kelembapan ingkang langkung dhuwur utawi langkung alit.
Apa tegesé tingkat bahaya?
Ing taun 1980-an, suhu rata-rata ing wewengkon iki 10 °C. Ing taun 1990-an, suhu rata-rata ing wewengkon iki 10 °C. Ing taun 2000-an, suhu rata-rata ing wewengkon iki 12 °C. Ing taun 2005, suhu rata-rata ing wewengkon iki 12 °C.
Apa kang dadi sebabé panasé bumi?
Ing mangsa panas, suhu ing pulo iki bisa tekan 30 °C. Ing mangsa salju, suhu bisa tekan 18 °C. Ing mangsa panas, suhu bisa tekan 20 °C. Ing mangsa salju, suhu bisa tekan 30 °C.
Mengapa kalkulator ngomong "no heat stress" ing dina panas?
Ing suhu 20 °C, suhu awak manungsa bakal dadi 100 kali luwih dhuwur tinimbang ing suhu 20 °C. Ing suhu 20 °C, awak manungsa bakal dadi luwih panas tinimbang ing suhu 100 °C. Ing suhu 20 °C, awak manungsa bakal dadi luwih adhem tinimbang ing suhu 100 °C.
Apa sing diarani panas lan apa sing diarani dingin?
Iki iku pambecikan kang kontras: indeks panas nambahake panas kang katon saka kelembapan ing cuaca panas, nanging angin dingin nyuda panas kang katon saka angin ing cuaca adhem. Indeks panas butuh suhu lan kelembapan; angin dingin butuh suhu lan kecepatan angin.
Ing basa Jawa, panas iku tegesé panas utawa panas srengéngé.
Kacal kanggé bayang-bayang. Cahya srengéngé langsung saged nambahi 15 °F kanggé suhu ingkang dipunrasa, saéngga nilai ingkang nyata dipunrasa-kaya ing luar ruangan nalika srengéngé penuh langkung dhuwur tinimbang angka ingkang dipunbalikaken kalkulator punika.
