Practical units used for measuring large masses:
1 tonne or I metric ton = 1000 kg
1 quintal = 100 kg
1 slug = 14.57 kg
1 pound = 1 lb = 0.4536 kg
1 Chandra Shekher limit = 1 CSL = 1.4 times the mass of the sun.
CSL is the largest practical unit of mass.
Practical unit used for measuring very small masses:
Atomic mass unit. It is defined as th of the mass of one 126C atom.
1 atomic mass unit = 1 amu = 1 u = 1.66 × 10-27kg
The mass of a proton or a neutron is of the order of one amu.
