so
same way

if the density is 13.6

the weight will be 13.6 kgwt

now you convert to mass

normal way

13.6/9.8

nearly 1.36 kg

but is it right

now mass=vol*density

if the density is 13.6

if the gravity changes to .1

density is 136

then one kg

so the liter is kg

basic way but density is no of times
