I noticed both 度 and 量 mean "amount, number". It looks like they are not exchangeable. Am I right?

For example, I saw 温度,湿度,长度,宽度,高度,角度, but never saw 温量,湿量,长量,宽量,高量,角量。I also feel 重量,容量,含量,数量 are fixed combinations too. Is there a rule about where to use which?

  • 小马词典:量:capacity; quantity; amount;度: extent; degree of intensity;typical examples 热量(heat),温度(temperature), more examples: 质量、力量、重量、产量、数量、含量、能量、、容量、流量 速度、程度、高度、强度、长度,浓度、密度、厚度、深度、宽度 – user6065 Nov 16 '17 at 22:42
  • , 程: degree, level, scale; , 计: measure, meterage, metric. 度 is used for ratio or value, 量 is used for volume of things generally, but it is not absolute, maybe the translation convention is different in different eras. – 賈可 Jacky Nov 17 '17 at 4:37
  • 热量 heat, 热度 temperature. more results showing how dictionaries distinguish between nouns 量 and 度:"汉语水平考试词典":量(名)[义1]数量;数目(quantity):~变|~词|~器|变~|常~(constant; numeric constant)|电~|动~|风~|计~|剂~|流~|微~|限~|度~衡(weights and measures)|限雨~|等~齐观(put on a par)|一定要保质保~地完成任务|这个港口的年吞吐~是八千万顿[义2]能够容纳或达到的限度(capacity):放~|海~|极~|食~|音~|老张饭~很大,一顿可以吃三四碗|男子汉气~不能太小,要大度一些。$度(名)表明物质的有关性质达到的程度(degree of intensity):亮~|热~|硬~|纯~|广~|宽~|这辆车的速~真快|那块板的后~正合适。[义2]表示可以计量的标准(degree):进~|坡~|桥的跨~不太大|做什么事都要适~,不要过~. – user6065 Nov 17 '17 at 11:07
  • @賈可Jacky The more examples I read, the more I believe there is actually no rules to differ these two words. – cnwang09 Nov 19 '17 at 16:59

度 is measurement for length, height or level (difference between levels is measured in distance )

量 is measurement for volume (something to do with space available or occupied)

As nouns, they are not interchangeable

量度 (v ) to measure ( length or volume)

量 (v) to measure ( length or volume)

度 (v) to measure ( length)

  • 度 is not just for measuring length. The counter examples are 温度,湿度,etc. – cnwang09 Nov 19 '17 at 2:11
  • I mentioned 度 measuring 'level' -温度 and 湿度 are measuring in '高' (high) or '低' (low). High is long length low is short length – Tang Ho Nov 19 '17 at 2:43

度 - measure length

量 - measure volume

衡 - measure weight
