The temperature of a fart at time of creation is 98.6 degrees Fahrenheit.

Farts Exit Your Body at Exactly 98.6°F

Your body is a fart furnace running at a precise 98.6 degrees Fahrenheit. When intestinal gas makes its grand exit, it's carrying that exact temperature with it—same as your blood, your liver, and every other part of your insides.

This isn't a coincidence. Farts are born deep in your digestive system, where bacteria feast on undigested food and produce gases like methane, hydrogen, and carbon dioxide. Down there in your intestines, everything operates at core body temperature. By the time that gas travels through your colon and reaches the exit, it hasn't had time to cool down.

Why Farts Feel Hot (Even Though They're Not)

Here's the weird part: 98.6°F farts often feel hot against your skin, even though they're technically body temperature. Your skin runs cooler than your core—typically between 90-95°F depending on the room. When 98.6-degree gas hits your cooler skin, the temperature difference creates that warm sensation.

Think of it like this: your internal organs are a cozy 98.6 degrees at all times. Your skin? It's constantly adjusting to your environment, rising and falling with room temperature. That's why a fart feels warmer after you've been sitting in air conditioning versus sweating in summer heat.

The 10-Feet-Per-Second Express

Temperature isn't the only impressive fart stat. Scientists have clocked flatulence traveling at roughly 10 feet per second as it exits the body. At 98.6 degrees and moving at highway speeds (relatively speaking), your digestive system is launching tiny heat-seeking missiles.

The average person produces about half a liter of fart gas daily, spread across 14-23 individual releases. Each one? A perfect 98.6-degree package, fresh from your internal oven.

So next time you're wondering why that fart felt warm, remember: it's not hotter than body temperature. Your body temperature is just hotter than your skin realized.

Frequently Asked Questions

What temperature is a fart when it comes out?
A fart is exactly 98.6 degrees Fahrenheit (37 degrees Celsius) when it exits your body—the same as your core body temperature.
Why do farts feel hot if they're body temperature?
Farts feel hot because your skin temperature (90-95°F) is cooler than your core temperature (98.6°F). The temperature difference makes the gas feel warm against your skin.
How fast does a fart travel?
Farts have been measured traveling at approximately 10 feet per second as they exit the body.
How many times does the average person fart per day?
The average person passes gas 14-23 times per day, producing about half a liter of gas total.
Where does fart temperature come from?
Farts are produced in your intestines where everything operates at core body temperature (98.6°F), and the gas doesn't cool down during its journey out.
