单位换算
Unit Conversions
在相关的标准计量单位(时间、长度、面积、体积/容积、质量)之间灵活换算,在适当情况下使用小数表示,最多保留三位小数。
Convert freely between related standard units of measurement (time, length, area, volume/capacity, mass) using decimal notation to up to three decimal places where appropriate
学习证据 / Evidence
- 利用线性比例因子的平方,在面积单位(如平方厘米和平方米)之间进行换算
- 完成多步换算(例如先把2.5小时换算成分钟,再换算成秒)
- 在体积单位之间进行换算(如把立方厘米换算成升),并解释它们之间的关系
- Convert between area units such as cm² and m² using the square of the linear scale factor
- Perform multi-step conversions (e.g. convert 2.5 hours to seconds via minutes)
- Convert volume units such as cm³ to litres and explain the relationship
