Checked against official Korean sources·Updated Oct 31, 2026

One Go Korea helps foreigners living in or visiting Korea get things done — renting a home, understanding a payslip, seeing a doctor, setting up a phone, enrolling a child in school — in plain English, in one go.

Who we are

We are One Go Korea Editors, a small team of Koreans living in Korea. Most English information about Korean rules is translated second-hand and goes out of date quickly. We read the original Korean sources first — government ministries, the National Tax Service, the National Health Insurance Service, Korea Immigration Service and the laws themselves — and then explain what they mean for you.

What you will find here

  • Guides to housing, money and work, health, daily life, family and school, and visiting Korea.
  • Korea calculators — Korean age, pyeong to square meters, salary take-home pay and real estate agent fees — built on current Korean rates.
  • Korea news that affects foreigners, explained with the background you need.

Our editorial rules

  • Every benefit or rule guide states whether foreigners qualify and which visa or residence status matters.
  • We link to the official source and show when a page was last checked.
  • Rates and figures are reviewed every January and whenever laws change.
  • We correct mistakes quickly. If something is out of date, please tell us.

How we check every guide

  1. Original source first: we read the Korean-language page of the ministry, agency or law (for example law.go.kr, nts.go.kr, nhis.or.kr, hikorea.go.kr) — never an English summary alone.
  2. Foreigner test: we check whether the rule applies to foreign residents and visitors, and under which visa or residence status.
  3. Numbers re-run: every figure and calculator result is recalculated against the official rate tables.
  4. Review before publishing: every guide is reviewed by an editor before it goes live, and the “Updated” date at the top of each page shows the last check.

Pyeong to Square Meters Calculator: Korean Apartment Sizes Explained (m² & sq ft)

Apartment ads and Korean friends still talk in pyeong (평) . Convert pyeong to square meters or square feet instantly, then see what "a 34-pyeong apartment" really means — and why the number on the listing is bigger than the space you actually get. The formula 1 pyeong = 400 ÷ 121 m² ≈ 3.3058 m² ≈ 35.58 sq ft. To go the other way, multiply square meters by 0.3025. Pyeong comes from an old East Asian unit equal to a square of 6 ja on each side — roughly the size of two tatami mats.
