4E4

4E4 is a designation used in several domains to refer to either a numeric value expressed in scientific notation or as a catalog or part code. In numerical terms, 4E4 denotes 4 × 10^4, which equals 40,000. In many programming languages and data formats, the same value can be written as 4e4 or 4E4, with the exponent written after the letter E. This convention, rooted in scientific and engineering notation, provides a compact way to represent large or small numbers.

Beyond pure mathematics and computing, 4E4 frequently appears as a model number or catalog identifier. In manufacturing, electronics, automotive parts, and other industries, 4E4 may designate a specific item within a supplier’s catalog. The exact meaning of the code depends on the issuer and the product line, so it does not carry a universal definition across industries.

4E4 can also appear in transportation, logistics, or service contexts as a route, service, or equipment designation. In such cases, the code is operational and company-specific rather than standardized.

Because 4E4 is highly context-dependent, interpreting it correctly requires examining the surrounding information—such as the documentation, catalog reference, or system in which it appears. Without this context, the code remains ambiguous and may refer to different things in different settings.

In summary, 4E4 most commonly represents the numeric value 40,000 in scientific notation, but it is also used as a flexible alphanumeric identifier in catalogs and systems, with its exact meaning determined by the issuing organization.
