The specific weight is the weight per unit volume of a substance, and it is given by multiplying the specific gravity by the specific weight of water.<\/p>\n\n\n\n<p>The specific weight of mercury is significantly higher than water&#8217;s because its density is much greater, which is why mercury sinks to the bottom of containers and exhibits high surface tension. This is a typical property of heavy metals. The formula used here relies on the direct proportionality between specific gravity and the specific weight of water, so knowing the specific gravity of a substance allows for an easy calculation of its specific weight.<\/p>\n\n\n\n<p>Let me generate an image to help visualize this concept.<\/p>\n\n\n\n<p>Here is a conceptual image showing the relationship between specific gravity and specific weight.
