113°F to °C: 113 Fahrenheit Is 45 Celsius
113°F = 45°C
113 degrees Fahrenheit is exactly 45 degrees Celsius. No rounding is needed: (113 − 32) × 5/9 = 81 × 5/9 = 45°C.
That is extreme heat, 14.4°F (8°C) above normal body temperature. Looking for the other direction? 113°C is 235.4°F.
How to Convert 113°F to °C (Step by Step)
The Fahrenheit to Celsius formula is:
°C = (°F − 32) × 5/9 (or equivalently, °C = (°F − 32) ÷ 1.8)
- Subtract 32: 113 − 32 = 81
- Multiply by 5/9: 81 × 5/9 = 405/9 = 45
- Result: 113°F = 45°C
Check it backwards: 45 × 9/5 + 32 = 81 + 32 = 113°F. ✓
For a homework question such as “113 °F = ? °C”, write the formula, substitute 113 for °F and show both steps exactly as above; the answer is 45 °C.

Is 113°F Hot? How Hot Is 45°C?
Yes, 113°F (45°C) is extreme, dangerous heat. For comparison, 113°F is:
- 81°F (45°C) above the freezing point of water (32°F / 0°C)
- 14.4°F (8°C) above normal human body temperature (98.6°F / 37°C)
- 9°F (5°C) above 104°F (40°C), the body temperature of a high fever
- 99°F (55°C) below the boiling point of water (212°F / 100°C)
Because the air is hotter than your skin (about 95°F / 35°C), it adds heat to your body instead of carrying it away, so evaporating sweat is the only way left to cool down. In dry desert air that works reasonably well in the shade with plenty of water; in humid air it does not, and the “feels like” temperature (heat index) climbs far above 113°F. For what 113°F feels like, heat-safety advice and warning signs of heat illness, see our guide to 113 degrees Fahrenheit weather.
Heat Safety
At 113°F (45°C), limit time outdoors, drink water regularly, rest in shade or air conditioning, and never leave children or pets in a parked car, where the inside gets much hotter than the outside air. Confusion, fainting, or hot skin with a very high body temperature can mean heat stroke: call emergency services immediately.
Where Has It Been 113°F (45°C)?
113°F is rare in most of the world, but in a few places it is a normal part of summer:
United States
- Death Valley, California: summer highs often reach or exceed 113°F, and it holds the official world record of 134°F (56.7°C), set in 1913.
- Phoenix, Arizona: reaches 113°F in most summers; its all-time record is 122°F (50°C), set in June 1990.
- Las Vegas, Nevada: reaches it during strong heat waves; its record is 120°F (48.9°C), set in July 2024.
Middle East & South Asia
- Kuwait and southern Iraq (for example Kuwait City and Basra): 45°C+ is common in July and August.
- Pakistan and northern India: pre-monsoon heat waves in May and June regularly push past 45°C.
Europe, Australia & Canada
- Southern Spain (the Guadalquivir valley around Seville and Córdoba) can pass 45°C in severe heat waves. Europe’s record is 48.8°C (119.8°F), set in Sicily in 2021.
- Inland Australia exceeds 45°C in many summers. The national record is 50.7°C (123.3°F).
- Lytton, British Columbia reached 49.6°C (121.3°F) in June 2021, Canada’s record.
Quick Mental Shortcut
For a rough estimate without a calculator, subtract 30 and halve: (113 − 30) ÷ 2 = 41.5°C. This underestimates hot temperatures (the exact answer is 45°C), so use the exact formula when it matters. A simple exact method: subtract 32, divide by 9, multiply by 5 → 81 ÷ 9 = 9, 9 × 5 = 45.
Other Temperature Conversions for 113
113°C to °F = 235.4°F
°F = (113 × 9/5) + 32 = 203.4 + 32 = 235.4°F. That is 13°C above the boiling point of water, a cooking or industrial temperature rather than a weather one. See the full 113°C to Fahrenheit conversion.
113°F to Kelvin = 318.15 K
K = (°F − 32) × 5/9 + 273.15 = 45 + 273.15 = 318.15 K.
113 K = −160.15°C = −256.27°F
°C = 113 − 273.15 = −160.15°C. That is cryogenic cold, but still warmer than the boiling points of liquid oxygen (−183°C) and liquid nitrogen (−196°C).
Fahrenheit and Celsius in Brief
- Fahrenheit (°F): proposed by Daniel Gabriel Fahrenheit in 1724. Water freezes at 32°F and boils at 212°F at sea-level pressure, a 180-degree span. Used mainly in the United States.
- Celsius (°C): based on the scale Anders Celsius proposed in 1742 (originally inverted, with 100 at freezing). Water freezes at 0°C and boils at 100°C, a 100-degree span. Used in most of the world and in science.
- Why 5/9: 100 Celsius degrees cover the same range as 180 Fahrenheit degrees, so 1°F = 5/9°C; the 32 accounts for the different zero points.
Frequently Asked Questions
What is 113°F in Celsius?
113 degrees Fahrenheit is exactly 45 degrees Celsius. Using °C = (°F − 32) × 5/9: (113 − 32) × 5/9 = 81 × 5/9 = 45°C.
How do you convert 113°F to °C?
Subtract 32 from 113 to get 81, then multiply by 5/9 (or divide by 1.8) to get 45. So 113°F = 45°C.
Is 113°F hot?
Yes. 113°F (45°C) is extreme heat. It is 14.4°F (8°C) above normal body temperature, so the air adds heat to your body instead of carrying it away. Weather services treat temperatures like this as dangerous, and heat exhaustion or heat stroke can develop with prolonged exposure, especially during exertion or in humid conditions.
Where has it been 113°F?
113°F (45°C) is a normal summer high in Death Valley, California, and is reached in most summers in Phoenix, Arizona. It is also common in summer in Kuwait and southern Iraq, and is reached in pre-monsoon heat waves in Pakistan and northern India. Southern Spain and inland Australia see it during strong heat waves.
What is 113°C in Fahrenheit?
113°C is 235.4°F, using °F = (°C × 9/5) + 32: 113 × 1.8 = 203.4, plus 32 = 235.4°F. That is above the boiling point of water. Do not confuse it with 113°F, which is 45°C. Full details: 113°C to °F.
Why does 113°F convert to a whole number in Celsius?
A Fahrenheit temperature converts to a whole Celsius number when (°F − 32) is divisible by 9. For 113°F, 113 − 32 = 81, which is 9 × 9, so 81 × 5/9 = 45 exactly, with no rounding.
How do I show the working for 113 °F = ? °C?
Write the formula °C = (°F − 32) × 5/9, substitute 113 for °F, then calculate: (113 − 32) × 5/9 = 81 × 5/9 = 405/9 = 45. Answer: 113 °F = 45 °C.
