113°F to °C: Convert 113 Fahrenheit to Celsius
113 degrees Fahrenheit (°F) equals 45 degrees Celsius (°C). The conversion from Fahrenheit to Celsius is calculated using the formula: °C = (°F - 32) × 5/9.
113°F = (113 - 32) × 5/9 = 81 × 5/9 = 45°C
How to Convert 113°F to °C: Step-by-Step Guide
Converting from Fahrenheit to Celsius is straightforward using the standard conversion formula. Let's break down the process step by step:
Fahrenheit to Celsius Conversion Formula
The formula to convert Fahrenheit to Celsius is:
°C = (°F - 32) × 5/9
Step 1: Subtract 32 from the Fahrenheit temperature
113°F - 32 = 81

The History and Science Behind Temperature Scales
Understanding the Fahrenheit and Celsius scales helps to contextualize temperature conversions like 113°F to 45°C.
Fahrenheit (°F) Scale
- Created by: Daniel Gabriel Fahrenheit, a German physicist, in 1724
- Reference points: Originally set with 0°F as the temperature of a mixture of ice, water, and ammonium chloride, 32°F as water's freezing point, and 96°F as approximate human body temperature
- Modern definition: The freezing point of water is 32°F and the boiling point is 212°F at standard atmospheric pressure
- Usage: Primarily used in the United States and a few other countries for everyday temperature measurement
Celsius (°C) Scale
- Created by: Anders Celsius, a Swedish astronomer, in 1742
- Originally: In Celsius's original scale, 0° was the boiling point of water and 100° was the freezing point (opposite of today's scale)
- Modern scale: The scale was reversed after Celsius's death, with 0° as the freezing point and 100° as the boiling point of water at standard atmospheric pressure
- Scientific name: Also known as the Centigrade scale or the Celsius scale
- Usage: Standard in most countries worldwide for everyday temperature measurement and in scientific applications
Key Conversion Points
These temperature points might help you remember and estimate Fahrenheit to Celsius conversions:
- Freezing point of water: 32°F = 0°C
- Room temperature: 68-72°F = 20-22°C
- Normal body temperature: 98.6°F = 37°C
- High fever: 104°F = 40°C
- Boiling point of water: 212°F = 100°C
Quick Estimation Method
For a rough estimate when converting Fahrenheit to Celsius, you can use this simple method:
- Subtract 30 from the Fahrenheit temperature (this is simpler than subtracting 32)
- Divide the result by 2 (simpler than multiplying by 5/9)
Using this method for 113°F: (113 - 30) ÷ 2 = 41.5°C, which is reasonably close to the exact value of 45°C.
Additional Temperature Conversions for 113
While we've focused on converting 113°F to Celsius, you might also be interested in other temperature conversions involving the number 113:
113°C to Fahrenheit
°F = (°C × 9/5) + 32
°F = (113 × 9/5) + 32
°F = 203.4 + 32
°F = 235.4°F
113°C equals 235.4°F, which is:
- Extremely hot, well above the boiling point of water (100°C/212°F)
- Temperature used in some baking and roasting applications
- Temperature that would cause immediate burns on contact
113 Kelvin to Celsius and Fahrenheit
°C = K - 273.15
°C = 113 - 273.15
°C = -160.15°C
°F = (°C × 9/5) + 32 = (-160.15 × 9/5) + 32 = -256.27°F
113 Kelvin equals -160.15°C or -256.27°F, which is:
- Extremely cold, far below freezing
- Below the boiling point of liquid oxygen (-183°C)
- Above the boiling point of liquid nitrogen (-196°C)
Frequently Asked Questions
Is 113°F dangerous for humans?
Yes, an air temperature of 113°F (45°C) is considered dangerous for humans. Prolonged exposure to this temperature can lead to heat-related illnesses including heat exhaustion and heat stroke, which can be fatal. Heat stroke can occur when body temperature rises above 104°F (40°C), and at an air temperature of 113°F, the body's cooling mechanisms (primarily sweating) may not be sufficient to maintain safe body temperature, especially with high humidity. This temperature requires precautions such as staying hydrated, seeking air-conditioned spaces, and minimizing physical exertion.
How hot is 113°F compared to the hottest recorded temperatures?
113°F (45°C) is very hot but not unprecedented. The highest reliably recorded air temperature on Earth is 134°F (56.7°C) at Furnace Creek Ranch in Death Valley, California, recorded on July 10, 1913. However, 113°F is frequently recorded in many desert regions worldwide during summer months. Cities like Phoenix, Arizona; Las Vegas, Nevada; and Kuwait City regularly experience temperatures of 113°F or higher during heat waves. For many temperate regions, 113°F would represent an extreme record temperature.
Why doesn't 113°F convert to a round number in Celsius?
113°F happens to convert to exactly 45°C, which is a round number. However, many Fahrenheit temperatures don't convert to round numbers in Celsius because the two scales have different zero points and different intervals. The Fahrenheit scale sets 32° as the freezing point of water and 212° as the boiling point (a 180-degree span), while the Celsius scale sets 0° as freezing and 100° as boiling (a 100-degree span). These different reference points and scales mean that only certain Fahrenheit values will convert to whole numbers in Celsius.
What would happen to water at 113°F (45°C)?
Water at 113°F (45°C) would feel very hot to the touch but would remain in liquid form, as it's well below water's boiling point of 212°F (100°C). This temperature is too hot for comfortable bathing (typical bath water is around 100-105°F or 38-40.5°C). Water at 113°F could cause burns with prolonged exposure, especially to sensitive skin. In nature, this temperature can be found in some hot springs and in shallow water bodies during extreme heat waves, potentially causing stress or death to aquatic organisms adapted to cooler temperatures.
How accurate is the conversion of 113°F to 45°C?
The conversion of 113°F to 45°C is mathematically exact using the standard conversion formula: °C = (°F - 32) × 5/9. Using this formula with 113°F gives: (113 - 32) × 5/9 = 81 × 5/9 = 45°C exactly. There's no rounding involved in this particular conversion, which makes it a convenient reference point to remember. Many Fahrenheit-to-Celsius conversions result in fractions or decimal values, but 113°F happens to convert to exactly 45°C.
