いま何度？って英語でなんて言うの？

「気温」はtemperatureですので、
気温を聞く時は
What's the temperature now？
と言います。

参考になれば幸いです。

どのくらい暑い/寒いの？

この言い方でも気温を聞くことができます。

会話例
A: How hot is it in Tokyo today?
A: 今日の東京はどのくらい暑いの？
B: It's over 35 degrees today.
B: 今日は35度を超えてるよ。

○度はdegrees と言います。
アメリカでは摂氏（Celcius）では無く華氏(Fahrenheit)を主に使用します。摂氏35度ですと、華氏だと約95度になります。

今 - now
何 - what
度 - temperature
全部まとめたら What temperature is it now?になります。 How hot is it now?もあります。

今すごい暑い。今何度？
It’s really hot right now. How hot is it now?

赤ちゃん寒くない？今何度？
Is the baby cold? What’s the temperature now?

These two sentences can be used interchangeably as both, "temperature," and, "hot/cold outside," can have the same meaning when structured correctly. Using the word, "outside," is completely optional as one would most likely understand that you're asking about outside regardless if you include it or not.

「いま何度？」は英語では一番分かりやすくて自然に言うのは「What's the temperature now?」他の言い方は「How many degrees is it?」となります。

A: Do you know what's the temperature now?
B: 24 degrees
A: 今は何度か知っている？
B: 24度

「How hot/cold is it?」も聞いても大丈夫ですが、気温を聞いていることが分からないかもしれない。ただ程度で答える可能性があります：とても、あまり、まあまあ　＋　寒い・暑い。

A: How hot is it now?
B: Very.
A: 今はどれぐらい暑い？
B: とても。

When you ask the question what is the temperature? To someone they can respond with telling you the temperature in celsius or fahrenheit. For example: The temperature at the moment is: 32 degrees celsius, so it's pretty hot at the moment!

You can use any of the above two questions to ask how hot it is at that moment in time.

Example;
- How hot is it at the moment?
- Is the temperature very hot?
- How is the weather?

When asking someone for specific details about the temperature, you can ask:

-How cold/hot is it?

-What is the temperature?
This is the most simple way to ask your question.

1. What's today's high/low?
   This question is a very casual way of asking what the temperature
   is going to be at either its highest or lowest.

2. What's the current temperature outside?
   The current temeperature means what is the weather like right now
   or at this very moment.

It is hot today.
It sure is.
How hot is it? Like, what I mean is, what is the temperature right now?

I hope this helps.
Have a great day.
