    • n zero The defect of all quantity considered as quantity; the origin of measurement stated as at a distance from itself; nothing, quantitatively regarded. Upon a thermometer or any similar scale zero is the line from which all the divisions are measured in the positive and negative directions. Upon the centigrade and Réaumur's thermometers, it is the point at which the mercury stands when the thermometer is plunged into a mass of melting ice coarsely pulverized, from which some makers allow the water to drain off, but it is better not to do so. For some years after a thermometer is made the zero is said to rise—that is, the melting-point of ice stands higher and higher upon the scale. Upon the Fahrenheit thermometer the distance on the glass stem between the melting-point of ice and the temperature of steam at one English atmosphere of tension is divided into 180 degrees, and 32 such degrees below the melting-point of ice is marked as zero.
    • n zero Hence—3. Figuratively, the bottom of the scale; the lowest point or ebb; a state of nullity or inanition.

The warring flags hang colourless a while;
Now midnight's icy zero feigns a truce
Between the signs and seasons, and fades out
All shots and cries. But when the great thaw comes,
How red shall be the melting snow, how loud the drums!
"Snow in Europe" by David Gascoyne
These boys of light are curdlers in their folly,
Sour the boiling honey;
The jacks of frost they finger in the hives;
There in the sun the frigid threads
Of doubt and dark they feed their nerves;
The signal moon is zero in their voids.
