16. CONVERTING QUEVENNE INTO BOARD OF 

 HEALTH LACTOMETER DEGREES 



Rule. Divide the Quevenne reading by .29. (See 

 P- 1340 



17. CONVERTING BOARD OF HEALTH INTO 

 QUEVENNE LACTOMETER DEGREES 



Rule. Multiply the Board of Health reading by 

 .29. (See p. 134.) 



18. CORRECTING BOARD OF HEALTH LACTOM-

 60 F. add .3, and for each degree below 60 F. sub- 

 tract .3. (Seep. 136.) 



19. CHANGING VOLUME INTO WEIGHT 



Rule. To convert a known volume of a liquid 

 into pounds when the specific gravity is known, mul- 

 tiply the specific gravity of the liquid by the weight 

 of an equal volume of water. Example : One gallon of 

 water weighs 8.33 pounds; what is the weight of a 

 gallon of milk whose specific gravity is 1.032? Mul- 

 tiplying 8.33 by 1,032, we have as the answer 8.6 

 pounds. 



20. CHANGING POUNDS OF MILK INTO QUARTS
