If you find yourself needing to quickly convert Celsius to Fahrenheit, here is a simple trick you can use: multiply the temperature in degrees Celsius by 2, and then add 30 to get the (estimated) temperature in degrees Fahrenheit.

69.8° Fahrenheit
Answer: 21° Celsius is equal to 69.8° Fahrenheit.
Remember that when you see a weather forecast on TV, in a newspaper or on the radio, that anything from 20 degrees upwards is going to be warm, above 25 degrees is hot, above 30 degrees is very hot.
In Celsius, 63 degrees is very hot. In Fahrenheit, 63 degrees is cooler than room temperature.
The average body temperature is 98.6 F (37 C). But normal body temperature can range between 97 F (36.1 C) and 99 F (37.2 C) or more. Your body temperature can vary depending on how active you are or the time of day. Generally, older people have lower body temperatures than younger people have.
Body temperature below 95°F (35°C) is considered abnormally low, and the condition is known as hypothermia. This happens when your body loses heat faster than it can produce heat. Hypothermia is a medical emergency, which if left untreated can lead to brain damage and cardiac failure.
Hypothermia is a medical emergency that occurs when your body loses heat faster than it can produce heat, causing a dangerously low body temperature. Normal body temperature is around 98.6 F (37 C). Hypothermia (hi-poe-THUR-me-uh) occurs as your body temperature falls below 95 F (35 C).
Sepsis. A drop in body temperature could be the symptom of sepsis. This occurs when your body starts fighting itself instead of an infection. It can damage to your tissues, shutdown your organs, and even lead to death.
| Method | Women | Men |
|---|---|---|
| Tympanic | 35.7–37.8 °C (96.3–100.0 °F) | 35.5–37.8 °C (95.9–100.0 °F) |
Typically, shivering stops between 86–90°F (30–32°C).
Expected Survival Time in Cold Water
| Water Temperature | Exhaustion or Unconsciousness in | Expected Survival Time |
|---|---|---|
| 50–60° F (10–16° C) | 1–2 hours | 1–6 hours |
| 40–50° F (4–10° C) | 30–60 minutes | 1–3 hours |
| 32.5–40° F (0–4° C) | 15–30 minutes | 30–90 minutes |
| <32° F (<0° C) | Under 15 minutes | Under 15–45 minutes |
People can freeze to death at any temperature under 32 degrees F (0 degrees C). Most hypothermia deaths occur in temperatures from 50 and 30 degrees F. Most cold-weather deaths are from days of exposure or short-term exposure to cold temperatures in wet conditions.
People may feel hot without a fever for many reasons. Some causes may be temporary and easy to identify, such as eating spicy foods, a humid environment, or stress and anxiety.
Can you have the coronavirus without a fever? Yes. A fever is one of the common symptoms of COVID-19, but you can be infected with the coronavirus and have a cough or other symptoms with no fever, or a very low-grade one — especially in the first few days.
If you're feeling too hot during the night, it may be because the temperature of your room is too warm. A 2012 research review found that exposure to heat during the night increases wakefulness and decreases slow-wave sleep and rapid eye movement sleep.
Night sweats are drenching sweats that soak clothes and bedding and disturb sleep. Night sweats occur when blood vessels expand, causing increased blood flow, and then contract. This causes a sudden wave of heat that spreads throughout the body, followed by sweating, reddening of the skin, and rapid heartbeat.
Leukemia and lymphoma are among the cancers associated with night sweats. Those associated with leukemia usually occur in conjunction with symptoms such as fatigue, weight loss, or excessive bruising. Leukemia-related sweats may also result from daytime fevers.
What Causes Night Sweats in Men? Our bodies want to stay at approximately the same temperature, a safe range called the thermoneutral zone. Temperatures lower than this zone cause us to shiver and raise our internal temperature, while higher temperatures provoke sweating to cool us down.
