Home < OpenIGTLink < ProtocolV2 < UnitSENSOR message can handle a part of unites defined in The International System of Unites (SI) in its 8-byte (or 64-bit) field. The field is designed to specifiy a unit consisting of SI-prefix (e.g. milli, micro, kilo etc...) and combination of SI-base and/or SI-derived unites. The bites in the field are assigned as follows:
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-...
