Kilokaloriein

Kilokaloriein is a term encountered in speculative science and some nutrition-related discussions to denote a unit of energy. It is not an officially recognized unit by the International System of Units or by standard nutrition authorities. In many of these contexts, kilokaloriein is defined as the amount of energy equal to one kilocalorie, equivalent to 4,184 joules, but presented with a distinct name to illustrate alternative unit systems or to support fictional world-building.

The term derives from the prefix kilo- applied to the root kalorie (calorie) and the suffix -in, a naming convention used in some hypothetical measurement schemes. In this usage, one kilokaloriein carries the same magnitude as one kilocalorie and thus serves as a synonym for practical purposes, though it is described as a separate unit to emphasize a separate measurement context or narrative setting.

Kilokaloriein is not adopted in nutritional labeling or scientific protocols, and no standard symbol or conversion rules beyond the basic equivalence to 1 kcal are established. Critics note that introducing a nonstandard unit can create confusion with existing terms such as calorie, kilocalorie, and joule, particularly for readers and practitioners outside speculative contexts.
