Confused by this sentence

体感温度は１ｍの風で１度下がってる聞いたことがある。

So what I understand is: I've heard that our body temperature decreases by one degree for every 1 m/s (?) of wind.

I'm not sure if what I wrote even makes sense, either... This windchill index thing is very confusing to me. Please suggest a more correct and natural-sounding translation if possible.

Thanks in advance! :)

No, it's not the body temperature, but the temperature that the body feels.
I'm not good at English, so I used translation, but is that okay?

Probably it should be (just a minor correction about in the middle:
体感温度は１ｍの風で１度下がるって聞いたことがある。

As the above poster mentioned, 体感温度 is the temperature that the body feels (as if it was), even though the thermometer says otherwise, due to wind chill factor added in. I’ve seen expressions like “feels-like temperature” or “RealFeel temperature” (from a certain US weather forecasting company).

- I’ve heard that 1-meter wind brings down the feels-like temperature by 1 degree.

So a 5-meter wind speed would bring it down by 5 degrees. And if it was originally Japanese text, this “degree” would most likely be degrees C by the way.

Thanks for your explanation, you two.

This is honestly the first time I've heard of this "feels-like temperature" thing, lol. Is that really 1-meter and not 1-mile/hour?
- I've heard that our windchill temperature decreases by 1C for each 1-meter wind.
Does this have the same meaning?

When we talk about wind speed in Japan it’s meter per second.

Different countries do different adjustments to come up with the temperature it “feels” like - humidity and wind factors. So I am not sure if there is an exact match, but you probably could call it “windchill temperature.”
