Convert kiloelectronvolt (keV) to gigajoule (GJ). Enter a value for an instant result, or use the examples and reverse conversion below.
Mechanical, electrical, thermal and particle energy.
Try a decimal, 1e-9, 1/3, or 5 1/2.
Enter a kiloelectronvolt value to calculate gigajoule with full internal precision before display rounding.
Auto trims unnecessary zeroes and uses scientific notation for extreme magnitudes. Use Digits to set the display precision; calculations retain full precision.
