About Tsubo
Tsubo is a Japanese traditional area unit used in architecture and property contexts; 1 tsubo is about 3.305785 m².
About Acre
The international acre is 4,046.8564224 m² by definition. Acres are standard for rural and suburban land in the US and still appear in UK property contexts.
How to convert tsubo to acres
1 tsubo is equal to 0.00081687729411 acre:
1 tsubo = (3.3057851239669422 m² ÷ 4046.8564224 m²) ac = 0.00081687729411 ac
Each tsubo is defined as 3.3057851239669422 m² and each acre as 4046.8564224 m², so one tsubo equals 3.3057851239669422 ÷ 4046.8564224 ac = 0.00081687729411 ac.
Let a(tsubo) be the numeric value of the same area measured in Tsubo (tsubo), and a(ac) the value in Acre (ac). Then:
a(ac) = a(tsubo) × (3.3057851239669422 / 4046.8564224)
Equivalently, divide by how many tsubo fit into one ac (m² per ac divided by m² per tsubo):
a(ac) = a(tsubo) ÷ 1224.1740677759999
Or: acre = tsubo ÷ 1224.1740677759999
Examples
Example #1: Convert 20 tsubo to acre
20 tsubo = 20 tsubo × (3.3057851239669422/4046.8564224) ac = 0.0163375459 ac
20 tsubo = 20 tsubo ÷ 1224.1740677759999 = 0.0163375459 ac
Example #2: Convert 50 tsubo to acre
50 tsubo = 50 tsubo × (3.3057851239669422/4046.8564224) ac = 0.0408438647 ac
50 tsubo = 50 tsubo ÷ 1224.1740677759999 = 0.0408438647 ac
Summary
To convert Tsubo to Acre, multiply the value in tsubo by the ratio of square meters per tsubo divided by square meters per ac. Equivalently: value_ac = value_tsubo × (3.3057851239669422 / 4046.8564224). Numerically, 1 tsubo equals 0.0008168772941063317 ac.
Relationship context
Both units belong to US customary / imperial area measures. Relationships such as 9 ft² per yd² and 43,560 ft² per acre are exact under standard definitions. This tool uses SI-based square-meter factors for consistency.
