Frequently Asked Questions
常见问题
- How accurate are the conversions? — Conversions use standard conversion factors with full floating-point precision. Temperature conversions use the exact formulas (°C = (°F - 32) × 5/9). Results are precise for all practical purposes.
- What units are supported? — Length: mm, cm, m, km, in, ft, yd, mi. Weight: mg, g, kg, t, oz, lb, st. Temperature: °C, °F, K. Area: cm², m², km², ha, ac, ft², yd².
- What is a hectare? — A hectare (ha) is a metric unit of area equal to 10,000 square meters or approximately 2.47 acres. It is commonly used for measuring land area.
- 换算精度如何? — 换算使用标准换算系数和完整浮点精度。温度换算使用精确公式(°C = (°F - 32) × 5/9),结果对所有实际用途都足够精确。
- 支持哪些单位? — 长度:mm、cm、m、km、in、ft、yd、mi。重量:mg、g、kg、t、oz、lb、st。温度:°C、°F、K。面积:cm²、m²、km²、ha、ac、ft²、yd²。
- 什么是公顷? — 公顷(ha)是公制面积单位,等于 10,000 平方米或约 2.47 英亩,常用于测量土地面积。
