Translate both parts of the text reading firstly how to convert temperature from

Fahrenheit scale to Centigrade scale.

MEASURING TEMPERATURE

I

On the Centigrade scale the *boiling point¹ of water is fixed at 100 (one hundred degrees), its *freezing point² is at 0 (zero). The equivalent points on the Fahrenheit scale are at 212 and by 32.

When it is necessary to convert temperature reading from the Fahrenheit scale to the Centigrade, we subtract 32 and multiply by 5/9.

Sometimes scientists use the Absolute Scale in which the temperature is measured in degrees Centigrade from the point at which molecular motion ceases. Absolute zero is -273.1 C.

II

For adequate heating when it is cooled outside the heating plant, including the necessary ducts, registers, piping, radiators, etc., must be able to keep all the rooms at 70° Fahrenheit, even if it is 20 or 30 degrees below zero outside.

7. Notes on the text:

1. boiling point - точка кипения

2. freezing point - точка замерзания

3. Fahrenheit ['fa:rǝnhait] scale - шкала, пpедложенная немецким физиком

Фаренгейтом.
