What are the temperatures for freezing water on the

The lower and upper fixed points of particular scale decided by the freezing point of water and boiling point of water at standard atmospheric pressure, For celsius scale, 0 The lower fixed point is 0 C so this is freezing point on the celsius scale 0 The lower fixed point is 100 C so this is boiling point on the celsius scale The interval between 0 0 C to 100 0 C is divided into 100 equal parts or divisions or each division value is 1 C For fahrenheit scale 0 The lower fixed point is 32 F so this is freezing point on the fahrenheit scale 0 The lower fixed point is 212 F so this is boiling point on the fahrenheit scale The interval between 32 0 F to 212 F is divided into 180 equal parts or divisions or each division value is 1 F .
