“One degree” is correct, as is “zero degrees”.

At 0°C, water exists in the solid-state. The freezing point of water is 0 °C. The liquid form of water starts to become solid (ice) at this temperature

Absolute zero, technically known as zero kelvins, equals −273.15 degrees Celsius, or -459.67 Fahrenheit, and marks the spot on the thermometer where a system reaches its lowest possible energy, or thermal motion. There’s a catch, though: absolute zero is impossible to reach.

Celsius, also called centigrade, scale based on 0° for the freezing point of water and 100° for the boiling point of water.

uncountable noun. Zero is a temperature of 0°. It is freezing point on the Centigrade and Celsius scales, and 32° below freezing point on the Fahrenheit scale. It’s a sunny late winter day, just a few degrees above zero. That night the mercury fell to thirty degrees below zero.

Longitudes are, therefore, imaginary circles that intersect the North and South Poles and the Equator. Half of a longitudinal circle is known as a Meridian. Meridians are perpendicular to every latitude. Unlike, latitudes, there is no obvious central longitude.

Each section from equator to pole is 90 degrees and two poles have 2 quarters of circle/globe hence 90X2 180 lattitudes. adding the Equator it becomes 181 latitudes. There are 360 longitudes in total +1 equator as we add 1 more in latitude and consider total number of latitudes are 181.

A prime meridian is the meridian (a line of longitude) in a geographic coordinate system at which longitude is defined to be 0°. Together, a prime meridian and its anti-meridian (the 180th meridian in a 360°-system) form a great circle. This great circle divides a spheroid into two hemispheres.

Lines of longitude, also called meridians, are imaginary lines that divide the Earth. They run north to south from pole to pole, but they measure the distance east or west. The prime meridian, which runs through Greenwich, England, has a longitude of 0 degrees.

 On the earth the circle of latitude is just the east-west circle that connects all the location with the given latitude. The position of the location along the circle of the latitude is given by its latitude. Circle of latitudes are called parallel because they run parallel to each other.
