संकल्पना:

विशिष्ट गुरुत्व  = \(\frac{Density\ of\ material}{Density\ of\ water }\)

\(Density, ρ=\frac mV =\frac{W}{gV} \)

जहाँ

w = तरल का वजन N में

g = गुरुत्वाकर्षण के कारण त्वरण (9.8 N)

V = mमें तरल का आयतन 

गणना:

दिया गया है:

V = 1 लीटर = 0.001 m3

w = 9.81 N

तब,

ρ = \(\frac{9.81}{9.81\ \times\ 0.001}\) = 1000

विशिष्ट गुरुत्व = \(\frac{1000}{1000}\) = 1

इस प्रकार, विशिष्ट गुरुत्व 1 है।
