What does one nanojoule represent?

One nanojoule is a unit of energy equal to 1×10⁻⁹ joules, often used to measure very small energy amounts such as laser pulses or microelectronic operations.

Where is the kilocalorie (thermochemical) unit commonly used?

Kilocalorie (th) is typically used for expressing energy in food nutrition labeling, dietary planning, metabolic studies, and certain thermal or chemical engineering contexts.

Why are values converted from nanojoules to kilocalories (th) usually very small?

Because nanojoules measure extremely tiny amounts of energy, when converted to kilocalories (thermochemical), which are much larger units, the resulting values tend to be minute.
