Zur Reduction der Lesungen des Bifilars und der Lloyd'schen Waage dienen die 

 Formeln: 



H = 2.0677 — 0.0002257 [(160 - L) - 4. 116 [t 

 V = 4.0485 + 0.0005263 (L— 70) 

 wobei L und L^ die Lesung an der Scala des Bifilars und der Lloyd'schen Waage. / und 

 t, die entsprechenden Temperaturen bedeuten.
