In legal practice, kilobytes describe digital file size in IT and outsourcing contracts, procurement specifications, disclosure exercises, court e-filing limits and data-protection records.
A kilobyte (
kb) is a unit of data most commonly understood in computing to equal 1,024 bytes (binary). Some vendors and marketing materials use the decimal sense of 1 kilobyte = 1,000 bytes. The term is a descriptive technical expression rather than one defined by legislation or case law, and usage is broadly consistent across England & Wales, Scotland, Northern Ireland and Ireland.
Drafting and negotiation points:
- Specify the unit precisely to avoid disputes: state whether 1 kilobyte means 1,024 bytes (binary) or 1,000 bytes (decimal), or use “kibibyte (KiB) = 1,024 bytes” for clarity.
- Distinguish bytes from bits. “KB” (kilobyte) measures data size; “kb”/“Kb” (kilobit) often measures network speed. 8 bits = 1 byte. Avoid the abbreviation “Kb” for kilobytes.
- Align any storage, bandwidth, data-cap or file-size limits, and pricing or service-level calculations, with the chosen definition.
Typical uses include specifying document size limits, storage quotas, export volumes in eDisclosure/eDiscovery, and data volumes in telecoms and cloud services.
