Fahrenheit to Celsius Chart: Common Temperatures for Cooking and Weather

I was standing by my oven, squinting at a recipe, and the numbers felt… wrong

I had a sheet pan in one hand and my phone in the other, and the recipe said 425°F and my oven was set to Celsius because, long story, I bought it used from a guy who “totally knew what he had” (he didn’t). I typed it into a converter, got 218.3°C, and then I did what everyone does: I rounded it, panicked, and wondered if I was about to ruin dinner.

And that’s basically why people keep a Fahrenheit to Celsius chart around. Not because we love math. Because you’re hungry, or you’re packing for a trip, or you’re trying to figure out if 30°C is “nice” or “I’m going to melt.”

So here’s the quick, practical chart, plus the tiny bit of math that makes it all make sense.

And yeah, you can absolutely just use a calculator. I built those because I got tired of retyping the same stuff.

The chart you actually need (cooking + weather)

If you only bookmark one thing, make it this table. It’s the stuff that comes up constantly: freezing, room temp, hot day, “turn the oven to 350,” and that sort of thing.

Common situation	Fahrenheit (°F)	Celsius (°C)	How it feels / what it means
Water freezes / icy roads	32	0	Freezing point. If it’s wet, it’s sketchy.
Cool day / light jacket	50	10	Not cold-cold, but you’ll notice it.
Comfortable room	68	20	Indoor “normal” for a lot of people.
Warm day	77	25	Pretty nice. Shorts start happening.
Hot day	86	30	Hot. If you’re working outside, pace yourself.
Very hot / heat warning territory	95	35	Oppressive. Shade and water aren’t optional.
Low oven / slow roast	300	149	Low and slow cooking.
Moderate oven	350	177	The famous “bake most things” temp.
Hot oven	400	204	Crispier, faster browning.
Very hot oven	450	232	Pizza, roasting, “watch it closely.”

One sentence that’ll save you: a “350°F oven” is about 175°C. Not exact, but close enough that your cookies won’t hate you.

If you want the exact conversion every time, use this:

. And if you’re going the other way (a lot of ovens and weather apps do), here’s the reverse:

The only formula you need (and why the “minus 32” is there)

I used to just accept the conversion like it was magic. Then I finally asked: why are we subtracting 32? Why not 30, or 40, or… whatever?

Here’s the deal: Fahrenheit and Celsius don’t start at the same “zero.” Celsius sets 0°C at water freezing. Fahrenheit sets 32°F at water freezing. So you have to slide the scale over by 32 before you do the stretch/shrink part.

And the 5/9 part? That’s the scale difference. A Celsius degree is “bigger” than a Fahrenheit degree. Specifically, 100 Celsius degrees from freezing to boiling, and 180 Fahrenheit degrees over that same span. So the ratio works out to 5/9.

So if you’re doing it on a napkin (or on a jobsite, or in a rental kitchen with weird appliances), it’s always: shift it, then scale it.

A worked example: converting 425°F for a recipe without overthinking it

This is the one that got me, because recipes love 425°F. It’s hot, it’s common, and it’s annoying to convert in your head.

Convert 425°F to °C:

1. Subtract 32: 425 − 32 = 393
2. Multiply by 5: 393 × 5 = 1965
3. Divide by 9: 1965 ÷ 9 = 218.33…

So it’s about 218°C. Most ovens won’t even let you set 218 exactly, so you’ll pick 220°C and move on with your life. That’s not “lazy,” that’s normal. The excessiveness of chasing decimals in cooking is how you end up stressed out for no reason.

And if you’re converting the other direction (say your air fryer is in Celsius and the recipe is in Fahrenheit, or vice versa), you can do it cleanly here:

.

So why does everyone get this wrong? Because they skip the “minus 32” part and just multiply, and that’ll put you way off. Like, “why is my bread raw in the middle” off.

Quick mental shortcuts (not perfect, but shockingly useful)

I’m not going to pretend you’ll always have time to do (F − 32) × 5/9. Sometimes you’re checking the weather while carrying groceries and you just want the vibe.

Here are the shortcuts I actually use:

• 0°C ≈ 32°F (freezing). Burn that into your brain.
• 20°C ≈ 68°F (comfortable room). If you travel, this one pays rent.
• 30°C ≈ 86°F (hot day). If you’re outside working, you’ll feel it.
• 180°C ≈ 350°F (moderate oven). This is the cooking anchor.
• If you’re near room temp, a rough trick is: double °C and add 30 to get °F. It’s not exact, but it’s in the ballpark.

That last one: 20°C → about 70°F (actual is 68°F). 25°C → about 80°F (actual is 77°F). Good enough for “do I need a hoodie?”

But if you’re doing anything where being wrong matters (food safety temps, candy stages, that kind of thing), don’t wing it. Use the calculator and be done.

Here are a few more tools people end up hopping between:

(because recipes love weird decimals)

(same problem, opposite direction)

(discounts, tips, “is this sale real?”)

(the catch-all when you’re bouncing between systems)

FAQ

What’s the fastest way to convert Fahrenheit to Celsius?

If you need exact: use

. If you’re doing it manually: subtract 32, then multiply by 5/9.

Why does 350°F show up in so many recipes?

It’s just a common “moderate oven” setting that bakes evenly without scorching too fast. Converted, it’s about 177°C, and most Celsius ovens call that 180°C.

Is 200°C the same as 400°F?

Not exactly.

• 200°C = 392°F
• 400°F = 204°C

In practice, they’re close enough that most home cooking won’t care, but if you’re trying to match a recipe precisely, convert it.
