Mechanical, electrical, thermal and particle energy.
Try a decimal, 1e-9, 1/3, or 5 1/2.
Enter a kiloelectronvolt value to calculate U.S. therm 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.
