1 mL为什么必须写成 1 cm3已有6人参与
|
||
| 1 mL, this is actually 1 mdm3 thus the double multiplier is millideci which cannot be rationalized. The correct form is 1 cm3. |

他回复了一大串，不知道啥意思Note there is a special rule in SI that does not allow double multipliers - four common cases to avoid are: 1 mL, this is actually 1 mdm3 thus the double multiplier is millideci which cannot be rationalized. The correct form is 1 cm3. A similar problem occurs with μL which should be replaced with mm3 The final common error is say 15 GL this is again a double multiplier giga-deci cubic metre and should be replaced by 15 hm3. {1 ML should be replaced by 1 dam3} Likewise 150 Mha is a double multiplier error mhm2, and since the hectare is a cadastral unit designed for farms and towns, such a large area should be replaced by 1 500 000 km2 If you are still having trouble with how to use these - ask your self why 1 km2 ≠ 1 000 m2 |
