BS 350:2004 - Conversion factors for units – BSI British Standards

BS 350:2004

Conversion factors for units

Status : Confirmed, Current   Published : May 2004



BS 350:2004 Conversion factors for units has now been updated, providing essential information on conversions to multiple units. With factual information, it provides an excellent source of reference to all users.

BS 350:2004 defines inter-conversion factors between units. As many imperial units are no longer officially used in the UK, this standard provides useful information that may be more difficult to find elsewhere especially when dealing with measurements that refer to old units.

Other conversion factors in this standard include:

  • Area
  • Time
  • Mass
  • Pressure
  • Energy
  • Volume
  • Velocity
  • Density
  • Power
  • Angles
  • Frequency
  • Force
  • Stress
  • Viscosity
  • Temperature.

Please note that the subjects covered in this revised standard are metrology, mechanics and heat. BS 350:2004 does not deal with purely electrical units.

BS 350:2004 replaces BS 350-1:1974, which has now been withdrawn.

Also available is BS 2856:1973 Precise conversion of inch and metric sizes on engineering drawings.
