What temperature is a fever in c?

My thermometer reads in Celsius, and my doctor usually talks in Fahrenheit. It's confusing to convert quickly. What temperature is a fever when measured in Celsius?

In Celsius, a fever is generally considered to be 38°C (which is 100.4°F) or higher for adults. It's a good threshold to remember. Keep a digital thermometer, it's accurate and easy to read. If it goes up, rest and hydrate, and see a doc if needed.

For kids, our pediatrician always says 38°C (100.4°F) and above is fever. I keep a Celsius thermometer at home because it's easier to track for prescriptions. If it crosses 38.5°C, I usually give medicine and call the doctor.

A fever in Celsius is typically 38°C or higher for adults. For those with PCOS, sometimes our bodies can react differently, so it's always good to be extra vigilant and consult your doctor if you're concerned, even for moderate temperatures.

This is important to know! So 38°C (100.4°F) is the benchmark. I always convert in my head to Fahrenheit because that's what I grew up with. But knowing it in Celsius makes it easier for international doctors too. Always good to be precise, especially with health.

I just had a fever last week, and my doctor told me to call if it went above 38.5°C. But the general starting point for a fever in Celsius is 38°C. Mine peaked at 39°C, and it felt horrible. Rest is key.

Honestly, at this point, if I'm sleeping badly, anything above 37°C feels like a fever! 😂 But yeah, doctors officially say 38°C (100.4°F) is the start of a fever. Just want to sleep it off, whatever the number is!
