AOne mu equals 666.67 square meters, or 0.0667 hectares, making 15 mu to the hectare. It remains the everyday land unit in China, so converting between mu and metric units is this tool's most common job.
AInternally every calculation uses the exact factors (1 hectare = 10,000 m², 1 acre = 4,046.8564224 m²); only the display is trimmed to a readable number of digits. For chained conversions always work from the source value, not the rounded output, to avoid drift.
AOne hectare is 10,000 m² and equals about 2.471 acres; conversely an acre is 4,046.86 m² or roughly 0.4047 hectares. Hectares dominate in metric countries while acres persist in the US and UK, so land listings frequently need this pair converted.
