Specific Gravity

As you well aware that all materials having individual properties and weights based on the density. How we can compare the different materials in a same platform. Since water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is the same number as density but without any units (adimensional).

A 1000kg of pure water = 1 cubic metre. Pure water was chosen as the 'base line' for specific gravity and given the value of 1. The specific gravity of all other materials are compared to water as a fraction heavier or lighter density. For example, beryllium has a specific gravity (sg) of 1.84 (1840 kg/cu.m) 

As specific gravity is just a comparison, it can be applied across any units. The density of pure water is also 62.4 lbs/cu.ft (pounds per cubic foot) and if we know that a sample of aluminium has a sg of 2.5 then we can calculate that its density is 2.5 x 62.4 = 156 lbs/cu.ft.
Note, kg/cu.m divided by 16.02 = lbs/cu.ft

One handy metric link between units to remember is that 1 Litre [1000cc] of pure water weighs 1 kilogram. Equally, 1 millilitre of pure water has a mass of 1 gram or 1mL = 1g. The upper-case L for litre is preferable as the lower case can be confused with the figure one, however it is common to see ml for millilitres on bottles.

Direction of Winds

Wind direction is the directions from which the wind is blowing or the direction from which the air is moving. Wind Direction indicates the compass direction from which the wind is blowing. Wind direction is illustrating using degrees from true north (360^o) to record direction.  The compass is divided into 360 degrees around the circle. The North position equals zero, and the degrees increase as you move around the compass clockwise until you reach 360 degrees back at the North position.

From the above picture on the compass below the letter N stands for North, S stands for South, E stands for East, and W stands for West. In order to be more specific, the letters NE are used for Northeast, SE for southeast, SW for Southwest and NW for Northwest. It is further divided NNE & ENE between first quarter. NNE stands for North Northeast and ENE stands for East Northeast. Please refer below table for abbreviation and the degrees.
