The energy required to break one bond in DNA is 10−20 J10^{-20}\text{ J}10−20 J. This value in eV is nearly:

0.006
Given 1 eV=1.6×10−19 J1\text{ eV} = 1.6 \times 10^{-19}\text{ J}1 eV=1.6×10−19 J. Therefore, 1 J=11.6×10−19 eV1\text{ J} = \frac{1}{1.6 \times 10^{-19}}\text{ eV}1 J=1.6×10−191 eV. So, 10−20 J=10−201.6×10−19 eV=0.06 eV10^{-20}\text{ J} = \frac{10^{-20}}{1.6 \times 10^{-19}}\text{ eV} = 0.06\text{ eV}10−20 J=1.6×10−1910−20 eV=0.06 eV.
