About Gigajoule

One gigajoule is 1,000,000,000 J. Utility-scale and fuel-system reporting commonly use GJ.

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.

How to convert gigajoules to electronvolts

1 gigajoule is equal to 6.24150907e+27 electronvolt when both are expressed in joule-equivalents:

1 gj = (1,000,000,000 J ÷ 1.602176634e-19 J) ev = 6.24150907e+27 ev

Each gigajoule is defined as 1,000,000,000 J and each electronvolt as 1.602176634e-19 J in this tool, so one gj equals 1,000,000,000 ÷ 1.602176634e-19 ev = 6.24150907e+27 ev.

Let d(gj) be the numeric amount in Gigajoule (gj), and d(ev) the amount in Electronvolt (ev). Then:

d(ev) = d(gj) × (1,000,000,000 / 1.602176634e-19)

Equivalently, divide by how many gj fit into one ev (joules per ev divided by joules per gj):

d(ev) = d(gj) ÷ 1.60217663e-28

Or: electronvolt = gigajoule ÷ 1.60217663e-28

Examples

Example #1: Convert 1 gj to electronvolt

1 gj = 1 gj × (1,000,000,000/1.602176634e-19) ev = 6.24150907446e+27 ev

1 gj = 1 gj ÷ 1.60217663e-28 = 6.24150907446e+27 ev

Example #2: Convert 10 gj to electronvolt

10 gj = 10 gj × (1,000,000,000/1.602176634e-19) ev = 6.24150907446e+28 ev

10 gj = 10 gj ÷ 1.60217663e-28 = 6.24150907446e+28 ev

Summary

To convert Gigajoule to Electronvolt, multiply the value in gj by the ratio of joules per gj divided by joules per ev. Equivalently: value_ev = value_gj × (1000000000 / 1.602176634e-19). Numerically, 1 gj equals 6.241509074460763e+27 ev.

Relationship context

You are converting between SI energy (joules) (Gigajoules) and atomic-scale energy (electronvolts) (Electronvolts). All values are mapped through joules first. The numeric factor is 6.241509e+27.
