About Electronvolt
The electronvolt is the energy change of one elementary charge across 1 V: 1 eV ≈ 1.602176634×10⁻¹⁹ J (exact by SI definition). Used in particle physics and chemistry.
About Gigajoule
One gigajoule is 1,000,000,000 J. Utility-scale and fuel-system reporting commonly use GJ.
How to convert electronvolts to gigajoules
1 electronvolt is equal to 1.60217663e-28 gigajoule when both are expressed in joule-equivalents:
1 ev = (1.602176634e-19 J ÷ 1,000,000,000 J) gj = 1.60217663e-28 gj
Each electronvolt is defined as 1.602176634e-19 J and each gigajoule as 1,000,000,000 J in this tool, so one ev equals 1.602176634e-19 ÷ 1,000,000,000 gj = 1.60217663e-28 gj.
Let d(ev) be the numeric amount in Electronvolt (ev), and d(gj) the amount in Gigajoule (gj). Then:
d(gj) = d(ev) × (1.602176634e-19 / 1,000,000,000)
Equivalently, divide by how many ev fit into one gj (joules per gj divided by joules per ev):
d(gj) = d(ev) ÷ 6.24150907e+27
Or: gigajoule = electronvolt ÷ 6.24150907e+27
Examples
Example #1: Convert 1 ev to gigajoule
1 ev = 1 ev × (1.602176634e-19/1,000,000,000) gj = 0 gj
1 ev = 1 ev ÷ 6.24150907e+27 = 0 gj
Example #2: Convert 10 ev to gigajoule
10 ev = 10 ev × (1.602176634e-19/1,000,000,000) gj = 0 gj
10 ev = 10 ev ÷ 6.24150907e+27 = 0 gj
Summary
To convert Electronvolt to Gigajoule, multiply the value in ev by the ratio of joules per ev divided by joules per gj. Equivalently: value_gj = value_ev × (1.602176634e-19 / 1000000000). Numerically, 1 ev equals 1.602176634e-28 gj.
Relationship context
You are converting between atomic-scale energy (electronvolts) (Electronvolts) and SI energy (joules) (Gigajoules). All values are mapped through joules first. The numeric factor is 1.602177e-28.
