APPENDIX F
UNIT CONVERSION
The Troxler Model 3451 Enhanced RoadReader Plus can display
measurement results in either SI (metric) units or English units.
Also, HM-181 of 49 CFR changes the standard units of radioactivity
in the United States from the English unit of curies (Ci) to the SI
unit of becquerel (Bq). This requires the shipper to convert the
activity on the Bill of Lading from curies to becquerels (GBq). Until
everyone is accustomed to the SI units, it is permitted to follow the
SI units with the English units in parentheses to clarify the
description [for example: 1.48 GBq (40 mCi)].
To help our users convert from English units to SI units, the table in
this appendix provides SI conversion factors for common English
units relevant to the 3451 gauge.
