About This Item
IEEE 268A-1980 is the IEEE International System of Units Conversion Factors Card, a compact reference focused on unit conversion for power, energy, and related engineering applications. It helps engineers, technicians, and procurement teams work with consistent SI-based values when comparing equipment data, preparing specifications, or checking calculations. As a superseded standard, IEEE 268A-1980 remains useful as a historical technical reference for documentation and legacy workflows.
Overview of IEEE 268A-1980
This standard presents a conversion factors card intended to support practical use of the International System of Units in technical work. In the context of power systems, electrical components, circuits, devices, and broader industrial applications, it offers a structured reference for translating measurements and ratings into consistent units. IEEE 268A-1980 is most relevant where accurate unit handling matters for design records, comparison of data sheets, and review of legacy engineering material.
Typical use cases
IEEE 268A-1980 may be used when reviewing electrical or energy-related specifications that require clear unit conversion across SI and non-SI values. It is relevant in power equipment documentation, component selection, test reporting, and the preparation of engineering calculations for systems and devices. The reference can also support maintenance teams, technical libraries, and organizations that still manage older drawings, tables, or procurement records where conversion consistency is important.
Why it matters
Consistent unit conversion reduces errors in design, testing, and technical communication. For engineering teams working with power and energy applications, a reliable reference like IEEE 268A-1980 helps improve clarity when comparing ratings, verifying calculations, and preparing compliant documentation. It can also support safer procurement and fewer misunderstandings between legacy and SI-based data, especially when historical materials are still part of the workflow.
