1. a unit of amount of substance equal to one thousand moles, used in chemistry and physics.
Usage: technical; symbol: kmol

Examples

• The chemical reaction required 2 kilomoles of sodium chloride.
• Engineers calculated the gas volume using kilomoles as the standard unit.
• One kilomole contains 6.022 × 10²⁶ particles.
• The laboratory ordered 5 kilomoles of pure oxygen for the experiment.
• In large-scale industrial processes, amounts are often measured in kilomoles rather than moles.
