How to Say “I lost _ kg(lbs).” in Japanese

How do you say “I lost 2kg.” in Japanese?

Today’s phrase is :

I lost _ kg.

_ キロやせたよ。

 _ kiro yasetayo

If you want to speak politely, you can say :

_ キロやせました。

 _ kiro yasemashita

When you want to say “I lost _ kg.”, put how much weight you lost just before “キロ kiro”.

“キロ” means “kilograms”.

As a unit of weight, we use kilograms, not pounds.

  • 1 kilogram = 2.205 pounds
  • 1kg = 1キロ ichikiro OR ikkiro
  • 2kg = 2キロ nikiro
  • 3kg = 3キロ sankiro
  • 4kg = 4キロ yonkiro
  • 5kg = 5キロ gokiro
  • 10kg = 10キロ jukkiro

For example, if you want to say “I lost 2kg.”, you can say like this :


 nikiro yasetayo

Or politely :


 nikiro yasemashita

  • I lost = わたしはやせました watashiwa yasemashita

We do not usually say “わたしは watashiwa (= I)” in everyday conversation.

_ キロ
_ kg

わたしは やせました
I lost
