45 Degrees Celsius to Fahrenheit Conversion

45°C in Fahrenheit is:
113°F Extreme Heat

How to Convert 45 Celsius to Fahrenheit: Exact Formula

To convert from Celsius to Fahrenheit, use the following formula:

°F = (°C × 9/5) + 32

Step-by-Step Calculation

  1. Start with the temperature in Celsius: 45°C
  2. Multiply by 9/5: 45 × 9/5 = 45 × 1.8 = 81
  3. Add 32: 81 + 32 = 113
  4. Result: 45°C = 113°F
45°C to Fahrenheit result: 45 degrees Celsius equals 113°F

About 45°C / 113°F: Temperature Facts and Significance

45°C (113°F) represents extreme heat conditions that are dangerous for humans and can cause serious heat-related illnesses. This temperature is:

  • Well above normal human body temperature (37°C/98.6°F)
  • Approaching the highest temperatures recorded on Earth
  • Dangerous for extended outdoor exposure
  • Capable of causing heat stroke within minutes

Safety Warning: Exposure to 45°C (113°F) temperatures can be life-threatening. Take extreme precautions in such conditions, including staying hydrated, seeking air conditioning, and limiting outdoor activities.

Understanding Extreme Heat Temperatures

45°C (113°F) represents dangerous heat conditions. Here's how it compares to other temperature levels:

Comfortable
20-25°C
68-77°F
Room temperature
Hot
30-40°C
86-104°F
Summer heat
Extreme Heat
40-50°C
104-122°F
Dangerous conditions (45°C falls here)
Temperature Range Classification Impact on Humans
20-25°C (68-77°F) Comfortable Ideal room temperature, comfortable for most activities
26-32°C (79-90°F) Warm Pleasant for outdoor activities with proper hydration
33-39°C (91-102°F) Hot Risk of heat exhaustion with prolonged exposure
40-45°C (104-113°F) Dangerous Heat High risk of heat stroke, dangerous for outdoor activities
46-50°C (115-122°F) Extreme Danger Life-threatening conditions, immediate medical risk
50°C+ (122°F+) Critical Maximum survival limit, immediate life threat

Note about human survival: The theoretical maximum wet-bulb temperature that humans can survive is about 35°C (95°F) at 100% humidity. At 45°C (113°F), even with low humidity, the risk of heat stroke is extremely high.

Safety Guidelines for 45°C (113°F) Conditions

When temperatures reach 45°C (113°F), take these precautions:

Seek immediate medical attention if you or someone else experiences symptoms of heat stroke: high body temperature, confusion, loss of consciousness, hot dry skin or profuse sweating, rapid pulse, or nausea.

Where 45°C Temperatures Occur

45°C (113°F) temperatures are typically found in:

Desert Regions

The world's hottest deserts regularly experience temperatures of 45°C and higher during summer months. Examples include the Sahara Desert, Arabian Desert, and deserts in Australia and the Southwestern United States.

Heat Waves

During extreme heat waves, regions that don't normally experience such high temperatures may reach 45°C. Climate change has increased the frequency and intensity of these events.

Industrial Settings

Some industrial processes, foundries, and manufacturing environments can reach 45°C, requiring special cooling systems and protective equipment for workers.

What About Negative 45°C?

While this page focuses on +45°C (113°F), some users search for negative temperatures. -45°C equals -49°F, which is extremely cold and found in polar regions during winter. Such temperatures present completely different dangers related to frostbite and hypothermia.

FAQs

Is 45°C hot or cold?

45°C (113°F) is extremely hot. It's well above normal human body temperature (37°C/98.6°F) and represents dangerous heat conditions. To put it in perspective, 45°C is:

  • Hotter than the highest temperature ever recorded in most European countries
  • Approaching the record temperatures in desert regions like Death Valley
  • Dangerous for human exposure without proper precautions
  • Capable of causing heat stroke within 30-60 minutes of exposure
What is 45°C in Fahrenheit?

45°C is equal to 113°F. The conversion formula is: °F = (°C × 9/5) + 32
Calculation: (45 × 9/5) + 32 = (45 × 1.8) + 32 = 81 + 32 = 113°F

Is 45°C a fever temperature?

No, 45°C (113°F) is not a fever temperature - it's far beyond what the human body can survive. The highest recorded human body temperature that someone has survived is approximately 46.5°C (115.7°F), and this was under exceptional medical care. Normal human body temperature is around 37°C (98.6°F), and a fever is typically considered to be 38°C (100.4°F) or higher.

Can humans survive 45°C weather?

Humans can survive in 45°C (113°F) weather with proper precautions, but it is dangerous. The key factors for survival are:

  • Access to shade or air conditioning
  • Adequate hydration (drinking plenty of water)
  • Limited physical activity during the hottest parts of the day
  • Appropriate clothing (light-colored, loose-fitting, breathable fabrics)
  • Acclimatization (people who live in hot climates adapt better to extreme heat)

Without these precautions, exposure to 45°C temperatures can lead to heat exhaustion or heat stroke, which can be fatal.

What is negative 45°C in Fahrenheit?

Negative 45°C (written as -45°C) is equal to -49°F. The conversion formula is the same: °F = (°C × 9/5) + 32
Calculation: (-45 × 9/5) + 32 = (-45 × 1.8) + 32 = -81 + 32 = -49°F

-45°C (-49°F) is extremely cold and found in polar regions during winter. Such temperatures present dangers related to frostbite and hypothermia rather than heat-related illnesses.

Where on Earth does it reach 45°C?

45°C (113°F) temperatures are typically found in:

  • Desert regions (Sahara, Arabian, Australian deserts)
  • Death Valley, California, USA (holds the record for highest temperature on Earth at 56.7°C/134.1°F)
  • Parts of the Middle East during summer months
  • Some regions in India and Pakistan during heat waves
  • Certain areas in Northern Africa

Due to climate change, more regions are experiencing 45°C temperatures during extreme heat waves, even in areas that didn't previously reach such highs.
