What is the attojoule used for?

Attojoule is used to express extremely small amounts of energy relevant at atomic, molecular, and single-photon levels.

Why convert attojoules to kilowatt-hours?

Converting attojoules to kilowatt-hours allows relating ultra-small energy values to common units used in electrical energy metering and billing.

Can I use this conversion for everyday electricity bills?

While kilowatt-hours are used for billing, attojoules represent very tiny energies not typically used directly in billing but useful for linking nanoscale values to practical units.
