科学都是测量和计数，表达某个量化数字是精确的或是有进位的，虽然这些不同的表达文字几乎没有什么差别，但还是有些细微的差别，作为一个仔细的作者在进行任何学术写作一定会考虑到这些。 about 和 approximately：
about ：常可分almost和nearly换用，但about用于表示时间、数量的"大约"时，实际数量可能多也可能少。 It costs about $10. 这大约要花10元钱。 They waited (for) about an hour. 他们等了一小时左右。 He arrived (at) about ten. 他是十点钟左右到的。
About 和 Approximately： About 通常會用在十倍數或五倍數的數字，因為人有五根手指，所以我們通常會把數字換成五或十的倍數。 因此，「Each plot contained about 17 trees」這個句子對於母語人士就會有點奇怪，矛盾的是 17 並不是 5 或 10 的倍數，也不像是折衷過的數字 ...

A round 有时出现在非正式的场合中同，代替approximately 和about:to go to bed around midnight; to invite aound fifteen people to a picnic. Roughly 通常在没有想要精确的真实意愿时，可替换approximately或about。【The cost of the car repaires was estimated at roughly two hundred dollars; the population of Delaware ...

aboutIt depends on how you use each word, as they all could be used in the same type of sentence. examples: 1. the temperature is about 10 degrees. 2. the temperature is around 10 degrees. 3. The temperature is approximately 10 degrees. However about can be used another way. examples: 1.Did you hear about the new iPhone?

這兩個詞有一定的相似性，但特點是approximately具有更正式的細微差別，與about相比，它呈現的數字更仔細。示例： There were about 50 people who came to the party! （聚會大約有 50 人!） 例子： The population of South Africa is approximately 58,560,000 million. （南非人口約為 5856 萬。
