What's the difference between
[“rei"冷](https://www.tanoshiijapanese.com/dictionary/index.cfm?j=rei) and
[“Samui”
寒い](https://www.tanoshiijapanese.com/dictionary/entry_details.cfm?entry_id=19925&j=Samui)
?

Both mean “cold”, but when would you use one over the other?

Please explain by giving reference to the below examples:

>   1. 冷凍用ビニール袋 (reitou-you Binīru fukuro)  
>  Freezer bag
>

>   2. 寒いです ( samui desu)  
>  It is cold

What's the difference between “rei" (冷) and “Samui” (寒い)?
Regarding the Kanji:

  * 冷 is for **objects** that are cold, such as drinks, food, or whatever _object_ you can think of.

  * 寒 applies to the temperature **around you** or the **atmospheric temperature** , not to the temperature of concrete objects.

Also take into account [user3856370's
warning](https://japanese.stackexchange.com/questions/86644/whats-the-
difference-between-rei-%E5%86%B7-and-
samui-%E5%AF%92%E3%81%84#comment139896_86644%3C). 冷{れい} (rei) is not a word
per se but it is usually a component of other words, whereas 寒{さむ}い (samui) is
an actual word meaning cold (weather-wise).

If you want to use 冷 as an adjective, as opposed to 寒{さむ}い (samui), the word
would be 冷{つめ}たい (tsumetai).

Compare both adjectives in the following sample sentences:

> 今日{きょう}は寒{さむ}い ! / (kyou wa samui! ) / It's cold today!

> このビールは冷{つめ}たくて 美味{おい}しい ! / (kono biiru wa tsumetakute oishii! ) This beer
> is cold and tasty!
