Hortvet vs. Celsius in Cryoscope

Hi, Dairy Scientists

How to convert degrees Celsius to Hortvet and vice versa?

Temp. reading in Celsius = 0.9656 x Temp. reading in Hortvet.

Temp. reading in Hortvet = 1.0356 x Temp. reading in Celsius.

Thus -0.512 Celsius = -0.530 Hortvet

Method of determining remaining milk when taking off cream

Hi, Dairy Farmers/Processors

I get asked a lot how much milk remains after cream is taken off - hope this calculation helps. If I did it wrong - please let me know :-) Theoretically:
1000 liters of milk(you start off with)40% fat in resulting cream(assume this is the fat % of your cream) Just substitute your cream’s tested fat % in here.


Problem 1:
What volume of milk remains when I take 3.8% butterfat milk down to 3.3%?(FULL CREAM)


3.8% - 3.3% = 0.5%

0.5% x 1000 liters = 500 parts of Fat removed

500 parts ÷ 40% cream = 12.5 Liters of cream

1000 – 12.5 =  987.5 liters milk remaining


Problem 2:
What volume of milk remains when I take 3.8% butterfat milk down to 2%?(LOW FAT)


3.8% - 2% = 1.8

1.8 x 1000 = 1800

1800 ÷ 40 = 45

1000 – 45 = 955 liters of milk remaining


Problem 3:
What volume of milk remains when I skim milk completely?


3.8% - 0% = 3.8%

3.8% x 1000 liters = 3800 parts of Fat removed

3800 parts ÷ 40% cream = 95 liters of cream

1000 – 95 = 905 liters of milk remaining

Kind regards,Leon the Milkman
