    Report No. DT-TM-1-60. ; FORWARD: The field of missiles and rockets deals with quantities of matter at various locations with different accelerations of gravity. The weight of these masses changes with gravity and the measurements of liftoff weight, fuel weight, etc., result in different values, depending on whether mass or weight units are used. Pressure and thrust are independent of the acceleration of gravity, but the instruments for measuring these values are calibrated with standard masses, producing different weight forces and calibration curves at different locations. Most sections of ABMA and other agencies or companies use pounds or kilograms as units of mass, weight or force, and the influences of different accelerations of gravity are often disregarded or treated incorrectly. These discrepancies become increasingly unacceptable with larger missiles and greater distances between operation sites. Therefore, the following Standard Procedure has been prepared to insure consistent and uniform terms and units of mass, weight, force, pressure and acceleration. All sections and individuals concerned are urged to use these units andprocedures. This is signed by Dr. Wernher von Braun, Director Development Operations Division.
