What does a nanojoule measure?

A nanojoule measures very small amounts of energy, equal to one billionth of a joule, often used in laser pulses or microelectronic systems.

Why convert nanojoules to watt-hours?

Converting nanojoules to watt-hours helps translate tiny energy measurements into standard units commonly used for electrical energy consumption and billing.

Can this tool be used for battery capacity calculations?

Yes, since watt-hours are used for battery ratings, converting nanojoules to watt-hours can aid in analyzing energy at very small scales relative to battery energy.
