This practice covers the use of the International System of Units (SI) in maritime applications as well as non-SI units commonly used and accepted for use with SI units. This practice is intended to establish uniform SI practice in the maritime industry. Covered in this practice are the concept of SI, the two units comprising SI (namely, base and derived SI units), SI prefixes, basic rules for style and usage of SI as well as methods for rounding and conversion of non-SI units to SI units. Conversion factors for quantities commonly used in the maritime industry are also provided.

1. Scope

1.1 This practice covers the use of SI, which is comprised of base and derived SI units. Also discussed are non-SI units that have been accepted and recognized by the CGPM as appropriate for limited use or time. Basic rules for style and usage of SI are set forth, as well as methods for conversion from non-SI units to SI units. Tables of quantities used by the marine industry are included, with present units and conversion factors given.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
