Answer: Zettanewton is the SI multiple of the force unit newton often expressed as 1021 newton .
Answer: 1 zettanewton is equal to 1.00E+21 newtons. Refer to ZN to N conversion
Symbol : ZN
So 1 zettanewton = 1.00E+21 newtons.
Example : 40 zettanewtons = 1.00E+21 x 40 newtons.
Or we can say, 40 ZN = 4.0E+22 N.
