What does 1 joule represent?

One joule is the energy transferred when a force of one newton moves an object one meter, and it equals one watt-second.

Why convert joules to megawatt-hours?

Converting joules to megawatt-hours allows translating small-scale scientific energy measurements into large-scale units used in electricity generation and utility billing.

Is megawatt-hour suitable for measuring small energy values?

No, megawatt-hours are large units and not appropriate for very small or instantaneous energy quantities.
