Formula: daa = ac × 4.04686
The conversion between acres and decares is essential for international land transactions and agricultural planning. With 1 acre equaling approximately 4.047 decares, understanding this relationship ensures accuracy in property measurements across different measurement systems. This conversion bridges Imperial land measurements used primarily in English-speaking countries with the metric-based decare system used throughout Europe and agricultural sectors worldwide.
Land measurement accuracy directly impacts property values, agricultural productivity calculations, and legal documentation. With 1 acre converting to 4.047 decares, errors in conversion can result in significant financial discrepancies in property transactions, incorrect crop yield projections, and compliance issues with international agricultural regulations. Precision in this conversion is critical for land surveyors, real estate professionals, and agricultural planners operating across different measurement systems.
Real estate professionals operating across international markets must convert property sizes accurately for comparable market analysis and pricing. European property listings typically use decares while North American properties use acres. Accurate conversion ensures proper valuation, prevents costly errors in property transactions, and enables transparent communication between buyers and sellers in different regions.
Agricultural professionals use decare measurements for yield calculations, fertilizer application rates, and crop rotation planning in European and Mediterranean farming regions. Converting between acres and decares is essential for farmers operating across different countries or consulting international agricultural data. Accurate conversion ensures proper resource allocation, regulatory compliance with EU agricultural subsidies, and optimization of farming operations.

Our calculator provides results with up to 10 decimal places for maximum accuracy.
One acre equals 4.04686 decares. This conversion factor comes from the relationship between Imperial and metric measurements: 1 acre = 4,047 square meters, and 1 decare = 1,000 square meters. Therefore, 4,047 ÷ 1,000 = 4.04686 decares. For quick mental calculations, using 4 decares per acre provides a reasonable approximation, though precise work requires the full factor for accuracy in financial and legal transactions.
Historical adoption of measurement systems created this divide. English-speaking countries and their former colonies adopted the Imperial system based on the acre, which originated in medieval England. European nations adopted the metric system and its land measurement derivatives (ares and decares) following the French Revolution. Today, this reflects broader measurement system choices: the United States, United Kingdom, and Commonwealth nations use Imperial units, while most of the world uses metric units. International trade and real estate require professionals to understand both systems.
