specific weight = weight/volume就是比重,单位是 (N/m^3或者 lb/ft^3)而gravity 指的是地心引力,所以不是用力来算的,而是用密度,所以,specific gravity=density /density of water @4 摄氏度,可翻译为相对密度,,没有单位(无量纲)。 结果一 题目 specific weight与 specific gravity的区别 答案 首先,weight...
The density of iron is 7850 kg/m3. The specific gravity of iron related to water with density 1000 kg/m3is SG (iron) = 7850 (kg/m3) / 1000 (kg/m3) =7.85 Example 5: Specific Weight of Water The density of water is 1000 kg/m3 at 4 °C (39 °F). ...

举例:The density ratio of the sample to water is 1.5. “specific weight”:虽然这个词不如“specific gravity”常用,但在一些特定领域,比如地质学,也可能用来指比重。 举例:The specific weight of the rock sample was measured to be 2.7.

specific gravity, 这个术语在英语中表示为 "比重"，在美语中则为 "specific gravity"。它的核心概念是物体的密度与其所在介质的密度之比。简单来说，它衡量的是一个物体相对于同体积水或其他标准物质的重量。当我们谈论物体具有"high specific gravity"时，这意味着这个物体的密度相对较大，比如重金属或...

The meaning of SPECIFIC GRAVITY is the ratio of the density of a substance to the density of some substance (such as pure water) taken as a standard when both densities are obtained by weighing in air. How to use specific gravity in a sentence.
