Square Feet to Pyeong Calculator

Convert square feet (sq ft, sqft, ft²) to Korean pyeong and square meters. Convert pyeong to square feet or calculate room size from width and length in feet.

Convert square feet (sq ft), pyeong (평), and square meters (m²) in one place. You can also enter a room's width and length to calculate its area in all three units.

1 pyeong = 400/121 m² ≈ 3.3058 m².
1 pyeong is approximately 35.58 sq ft.
Square meters are used for official property area in South Korea, while pyeong remains familiar in everyday housing conversations.

Square Feet to Pyeong Calculator

The Square Feet to Pyeong Calculator converts square feet (sq ft, sqft, ft²) into the Korean area unit pyeong (평). It also converts pyeong to square feet and shows the equivalent area in square meters (m²).

Use this calculator to compare Korean apartment sizes, homes, offices, hotel rooms, floor plans, and real-estate listings with familiar U.S. square-foot measurements. You can enter an area directly or calculate the area from a room's width and length.

What is a pyeong?

Pyeong (평) is a traditional Korean unit of area that is still commonly used when people talk about apartment, house, and office sizes in South Korea.

One pyeong equals

\frac{400}{121}\text{ m}^2

, or approximately

3.3058\text{ m}^2

. In U.S. units, one pyeong is approximately

35.58\text{ sq ft}

This makes pyeong useful when comparing a Korean property listing with a U.S. listing. Official Korean property areas are generally shown in square meters, while pyeong remains a familiar way to describe the overall size of a home in everyday conversation.

Square Feet to Pyeong Formula

To convert square feet to pyeong, use either of the following equivalent formulas.

\text{pyeong} = \text{square feet} \times 0.028103

\text{pyeong} = \frac{\text{square feet}}{35.58}

To convert in the opposite direction:

\text{square feet} = \text{pyeong} \times 35.58

These are the same formulas used by the calculator above.

Square Feet to Pyeong Examples

For example, 500 sq ft converts to approximately:

500\text{ sq ft} \approx 14.05\text{ pyeong}

500\text{ sq ft} \approx 46.45\text{ m}^2

A 1,000 sq ft space converts to approximately:

1{,}000\text{ sq ft} \approx 28.10\text{ pyeong}

1{,}000\text{ sq ft} \approx 92.90\text{ m}^2

Pyeong to Square Feet Conversion Chart

If a Korean apartment or office listing gives the size in pyeong, use this table to quickly estimate the equivalent size in square feet and square meters.

Pyeong	Square feet	Square meters

5 pyeong	177.9 sq ft	16.53 m²
10 pyeong	355.8 sq ft	33.06 m²
15 pyeong	533.7 sq ft	49.59 m²
20 pyeong	711.7 sq ft	66.12 m²
25 pyeong	889.6 sq ft	82.64 m²
30 pyeong	1,067.5 sq ft	99.17 m²
40 pyeong	1,423.3 sq ft	132.23 m²
50 pyeong	1,779.2 sq ft	165.29 m²

Why 84 m² Does Not Always Match the Pyeong Size You Hear in Korea

A direct mathematical conversion of

84\text{ m}^2

is approximately

25.41\text{ pyeong}

. However, you may hear an 84 m² Korean apartment described using a larger pyeong class.

This difference occurs because the pyeong figure used in everyday Korean real-estate conversations may refer to a broader supplied area that includes a share of common space. The

84\text{ m}^2

figure may instead refer to the unit's exclusive-use area.

Therefore, when comparing Korean apartment sizes, do not assume that the pyeong figure is always a direct conversion of the exclusive-use square-meter value.

How to Compare Korean Apartment Sizes with U.S. Square Feet

If you are comparing a Korean apartment, officetel, house, or office with a U.S. property, use the following process.

Find the area shown in square meters (m²) on the Korean property listing or contract.
Convert the square-meter value to square feet for a familiar U.S. comparison.
Check the corresponding pyeong value to understand how the property size may be described in Korea.
Make sure both properties use the same type of area measurement before comparing size or price per area.

Room Size Calculator: Feet to Pyeong

The calculator can also determine a room's area when you only know its width and length in feet. Select Room dimensions, enter both measurements, and the calculator will show the result in square feet, pyeong, and square meters.

For example, a room measuring

12\text{ ft} \times 10\text{ ft}

has an area of:

12\text{ ft} \times 10\text{ ft} = 120\text{ sq ft}

The equivalent Korean and metric areas are approximately:

120\text{ sq ft} \approx 3.37\text{ pyeong}

120\text{ sq ft} \approx 11.15\text{ m}^2
