If the units of mass, length and time are 100g,20cm and 1min respectively the equivalent energy for 1000erg in the new system will be the following:

1 Joule = 107 ergs
1 ergs = 10-7 J
1000 ergs = 10-4 J
= 10-4 Kg.m2.s-2
= 10-4 (10x100g).(20x25x20 cm2).(1/60 min)-2
= 10-3 (100g).25(20cm)2.(3600)min-2
= 25 x 10-3.(3600) .(100g)(20cm)2. min-2
= 90 New Unit
