이사하거나 집볼때 한번씩은 불편하셧을 평수계산!!

평소에 자주 쓰는 이 평수라는 단위. 문제는 우리가 이 평에 너무 익숙해져서  ㎡ 라고 써있으면 도대체 얼마나 되는지

한 번에 감이 안 온다는 문제가 있습니다

Calculating the square footage can be inconvenient at times when moving or looking at a house!! This commonly used unit is pyeongsu. The problem is that we have become so accustomed to this rating that if it is written as ㎡, how much is it? I have a problem where I can’t feel it all at once.

 

이제부터는 이렇게 해보세요

그냥 뒷자리를 빼고 3을 곱하는 겁니다.

예를 들어

40㎡로 돼 있다면 뒷자리인 0을 빼고 남아있는 4에 3을 곱하는 거

죠.그럼 12 평이 되는겁니다

ex) 40㎡  4X3 = 12

Try this from now on Just remove the last digit and multiply by 3.

for example If it is 40㎡, subtract the last digit, 0, and multiply the remaining 4 by 3. Yes, then it will be 12 pyeong. ex) 40 4X3 = 12

 

사실 아주 정확하게 계산하면 1평에 3.3057㎡니까 원래는 12.1 평인데요.
In fact, if you calculate it very accurately, 1 pyeong is 3.3057㎡, so it is originally 12.1 pyeong.

이 정도면 거의 차이가 없는 수준일겁니다

근데 딱 하나 추가로 아셔야 할 게 있는데

At this level, there will be almost no difference. But there is just one more thing you need to know.

ex) 56㎡, 57㎡, 58㎡,59㎡

지금처럼 뒷자리가 5보다 크다면 빼는 게 아니라 반올림을 해줘야합니다.

뒤에숫자 6,7,8,9를 버리는 게 아니라 앞자리 하나 올리는 거죠.

ex) 59㎡ 라면 6 X 3 = 18 평

그럼 5가 아니라 6이 되고  여기에 아까처럼 3을 곱해주면 됩니다.

그럼 6X3  18 평이죠 계산기로 정확히 해보면 17.84평 인데

이 정도면 1초 만에 암산한 것 치고는 아주 훌륭하니 활용해보세요

ex) 56㎡, 57㎡, 58㎡, 59㎡ Like now, if the last digit is greater than 5, you should round it up instead of subtracting it.

Instead of throwing away the numbers 6, 7, 8, and 9, you raise the first digit.

ex) 59㎡ Ramen 6 Then it becomes 6 instead of 5, and you can multiply this by 3 as before. Then, 6

This is pretty good for a mental calculation you did in just 1 second, so try using it.
