Specific gravity (SG) is a lot simpler than you and your alien friends expected: It's just the ratio of the density of a given object to the density of waterat a specific temperature.Specific gravity has no units.Its utility lies in the fact that the density of some objects changes with...
density = mass / volume You can rewrite the equation to solve for mass: mass = volume x density Densityof liquids usually is expressed in units of g/ml. If you know the density of a liquid and the volume of the liquid, you can calculate its mass. Similarly, if you know the mass an...

A physics term closely related to density is specific gravity (SG). This is just the density of a given material divided by the density of water. The density of water is defined to be exactly 1 g/mL (or equivalently, 1 kg/L) at normal room temperature, 25 °C. This is beca...
Specific gravity is the density of a substance divided by the density of water. Once you know density, you know mass per unit volume, and from that you can determine the weight. In the imperial measurement system, you have to convert the mass in slugs to weight in pounds. ...

The specific gravity stands for a dimensionless unit that defines the ratio of density of a substance to the density of water. The density of water is 1000 kg/cubic meters at 4 Celsius. In physics, the weight of the substance differs from its mass. The w

density = mass/volume The mass is usually the easy part while finding volume can be tricky. Simple shaped objects are usually given in homework problems such as using acube, brick or sphere. For a simple shape, usea formulato find volume. For irregular shapes, the easiest solution is to ...
自酿啤酒HowtoBrew中英对照4.pdf,前言 目前可以找到有關自釀啤酒( homebrewing )的好書有很多,那麼你會問:為什麼還 要再寫一本呢?答案是:這是觀點的問題。幾年前當我開始自釀啤酒的時候,我閱讀了每 一本我能找到有關啤酒釀造的書,這些書的出版時間前後相差達十五年
