How to use this calculator

  1. Enter the area in pyeong as shown on the property listing.
  2. Read the equivalent in square meters, the metric standard.
  3. Use the square-feet line if you're comparing with US listings.

Formula

m² = pyeong × 3.305785
  • pyeong — Korean area unit (1 pyeong = 6 × 6 ja)
  • 3.305785 — m² in one pyeong

Worked example

A 25-pyeong apartment equals 25 × 3.305785 ≈ 82.64 m² (about 890 ft²) — a common mid-size two-bedroom in Korea.

Frequently asked questions

What is a pyeong?

Pyeong is a traditional Korean unit of area used in real estate, equal to about 3.3058 square meters (a square roughly 1.818 m on each side). It remains common in property listings even though metric units are official.

How do I convert pyeong to square meters?

Multiply the number of pyeong by 3.305785. For example, 30 pyeong is 30 × 3.305785 ≈ 99.17 m².

How do I convert square meters back to pyeong?

Divide square meters by 3.305785 (or multiply by 0.3025). So 100 m² is about 30.25 pyeong.

Is pyeong the same as the Japanese tsubo?

Yes — pyeong and tsubo are the same size, both about 3.3058 m². The names differ by country.

Why is the floor area in listings sometimes larger?

Korean listings may quote supply area (gonggeup), which includes shared spaces like hallways, versus the exclusive (jeonyong) area you actually live in. Confirm which figure a listing uses.

Is pyeong an official unit?

No — South Korea adopted the metric system officially, but pyeong persists in everyday real-estate conversation, so conversions remain useful.
