113 Fahrenheit to Celsius: Temperature Conversion Guide
113 degrees Fahrenheit (°F) equals 45 degrees Celsius (°C). This conversion 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 Fahrenheit to Celsius
Converting from Fahrenheit to Celsius requires a simple two-step process. Let's break down the conversion of 113°F to °C step by step:

Climate Change and 113°F (45°C) Temperatures
With global climate change, temperatures of 113°F (45°C) are becoming more common and occurring in regions that previously rarely experienced such extreme heat:
- Europe has seen increasing instances of temperatures approaching or exceeding 45°C in recent years, particularly in southern regions
- The frequency of days exceeding 45°C has increased significantly in the Middle East and North Africa
- Heat dome events have pushed temperatures to unprecedented levels in typically temperate regions like the Pacific Northwest of the US and Canada
- Climate models predict that temperatures of 45°C and above will become more frequent in many populated areas by mid-century
Practical Implications of 113°F (45°C)
Understanding how a temperature of 113°F (45°C) affects various aspects of daily life is important for safety and planning:
Human Comfort and Survival
Temperatures of 113°F (45°C) exceed human comfort levels significantly and can be life-threatening without proper precautions:
- Humans cannot survive prolonged exposure without shelter and hydration
- Sweating may not effectively cool the body at high humidity levels
- Core body temperature can rise to dangerous levels quickly
- Most outdoor activities should be avoided
Infrastructure Impact
Extreme heat of 113°F (45°C) affects infrastructure and systems:
- Power grids may face brownouts or blackouts due to high cooling demand
- Roads and railways can buckle or warp
- Airport operations may be restricted (hot air is less dense, affecting lift)
- Electronics and machinery may overheat and malfunction
Water Resources
Water becomes critically important at 113°F (45°C):
- Evaporation rates from water sources increase dramatically
- Water consumption for cooling and hydration rises substantially
- Reservoirs and water supplies may deplete more quickly
- Agricultural needs increase while availability may decrease
Energy Consumption
Energy usage patterns change significantly at 113°F (45°C):
- Air conditioning systems run constantly and at maximum capacity
- Electricity demand peaks, often straining supply capabilities
- Cooling efficiency decreases at extreme outdoor temperatures
- Energy costs typically rise during extreme heat events
Safety Tips for 113°F (45°C) Weather
If you must deal with 113°F (45°C) temperatures, follow these important safety guidelines:
Stay Hydrated
Drink water regularly, even if not thirsty. Aim for at least 2-4 glasses (16-32 ounces) per hour when active outdoors.
Limit Outdoor Exposure
Stay indoors during the hottest part of the day (typically 10 AM to 4 PM). If outdoor activities are necessary, keep them brief.
Use Cooling Methods
Utilize air conditioning, fans, cold showers, or cooling centers. Place damp cloths on neck, wrists, and head.
Wear Appropriate Clothing
Choose lightweight, light-colored, loose-fitting clothing. Cover your head and use sunscreen when outdoors.
Monitor Vulnerable People
Check regularly on elderly, sick, or isolated people. Never leave children or pets in vehicles.
Recognize Warning Signs
Know the symptoms of heat-related illness: headache, dizziness, nausea, confusion, high body temperature, and lack of sweating.
Common Temperature Conversion Formulas

Frequently Asked Questions
Is 113°F (45°C) a dangerous temperature for humans?
Yes, 113°F (45°C) is considered a dangerous ambient temperature for humans, especially with prolonged exposure. At this temperature, the risk of heat-related illnesses like heat exhaustion and heat stroke increases significantly. Without proper hydration, shade, and cooling methods, the human body can quickly become overwhelmed as it struggles to maintain normal body temperature. This is especially dangerous for vulnerable populations such as the elderly, children, and those with certain health conditions.
What is the highest temperature ever recorded on Earth?
The highest reliably recorded temperature on Earth is 134°F (56.7°C), measured at Furnace Creek Ranch in Death Valley, California, USA, on July 10, 1913. This record has stood for over a century. More recently, temperatures of 129.2°F (54°C) were recorded in Mitribah, Kuwait in 2016 and 128.3°F (53.5°C) in Turbat, Pakistan in 2017, making them among the highest reliably measured temperatures in modern times.
Why do the US and a few other countries use Fahrenheit instead of Celsius?
The US and a few other countries (such as the Bahamas, Belize, and the Cayman Islands) use Fahrenheit largely due to historical reasons and cultural inertia. The Fahrenheit scale was developed in the early 18th century by Daniel Gabriel Fahrenheit and was widely adopted before the Celsius scale was created. When most countries moved to the metric system (including Celsius) in the 19th and 20th centuries, the US maintained its customary units, including Fahrenheit, due to the economic costs of conversion and cultural resistance to change.
How much water should I drink in 113°F (45°C) weather?
In 113°F (45°C) weather, you should significantly increase your water intake to prevent dehydration. Experts recommend drinking at least 1 liter (about 4 cups) of water per hour when exposed to such extreme heat, especially if you're active outdoors. Listen to your body's signals and drink before you feel thirsty, as thirst is already a sign of dehydration. Electrolyte-enhanced beverages may also be beneficial if you're sweating heavily, but avoid alcohol and caffeinated drinks as they can contribute to dehydration.
How does humidity affect how 113°F (45°C) feels?
Humidity dramatically affects how 113°F (45°C) feels to the human body. In dry conditions, sweating effectively cools the body as moisture evaporates from the skin. However, in high humidity, sweat cannot evaporate efficiently, preventing the body's natural cooling mechanism from working properly. This creates a much higher "feels like" temperature, often expressed as the heat index. For example, 113°F with 40% humidity feels like 136°F (58°C) to the human body, making it extremely dangerous. High humidity at high temperatures significantly increases the risk of heat-related illnesses.
