16. CONVERTING QUEVENNE INTO BOARD OF 

 HEALTH LACTOMETER DEGREES 



Rule. — Divide the Quevenne reading by .29. (Sec 

 p. 126.) 



17. CONVERTING BOARD OF HEALTH INTO 

 QUEVENNE LACTOMETER DEGREES 



Rule. — Multiply the Board of Health reading by 

 .29. (See p. 126.) 



18. CORRECTING BOARD OF HEALTH LACTOM- 

 ETER READING FOR TEMPERATURE 



Rule. — For each degree F. of temperature above 

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

 tract .3. (See p. 128.) 



19. CHANGING VOLUME INTO WEIGHT 



Rule. — To convert a known vohime of a liquid 

 into pounds when the specific gravity is known, mul- 

 tiply the specific gravity of the liquid by the zveighl 

 of an equal volume a/ zuater. 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 



Rule. — Divide the number of pounds of milk by 2.1^. 

 Example: How many quarts of milk in 100 pounds?
