Frequently Asked Questions
How accurate is the conversion?
The converter uses the exact ratio 1 pyeong = 400/121 m² (about 3.305785 m²), not a rounded constant such as 3.3058. The math is done with exact integer arithmetic, and only the final result is rounded.
Why can a "○○-pyeong" listing differ from the m² size I convert?
Listings usually quote the supply area, which is the exclusive-use area plus a share of common residential space such as hallways and stairwells. If you convert an exclusive-use area in m² into pyeong, the result can be smaller than the pyeong figure in the listing. This tool only applies the conversion formula (1 m² = 0.3025 pyeong, so 100 m² = 30.25 pyeong), so check which kind of area a figure refers to before comparing.
How are the results rounded?
Results are shown to two decimal places and rounded half up, so 0.005 and above rounds up. You can enter up to 6 decimal places and any value from 0 to 1,000,000,000.
Which box can I type in?
Either one. Type in the Pyeong box to get square meters, or in the Square meters box to get pyeong — the other box updates instantly.
