Most water in Earth's atmosphere and crust comes from saline seawater, while fresh water accounts for nearly 1% of the total. The vast bulk of the water on Earth is saline or salt water, with an average salinity of 35‰ (or 3.5%, roughly equivalent to 34 grams of salts in 1 kg of seawater), though this varies slightly according to the amount of runoff received from surrounding land.
In the United Kingdom, proof is 1.75 times the number (expressed as a percentage). [ 23 ] [ 20 ] For example, 40% alc/vol is 80 proof in the US and 70 proof in the UK. However, since 1980, alcohol proof in the UK has been replaced by alc/vol as a measure of alcohol content, avoiding confusion between the UK and US proof standards.
Relative humidity is normally expressed as a percentage; a higher percentage means that the air–water mixture is more humid. At 100% relative humidity, the air is saturated and is at its dew point. In the absence of a foreign body on which droplets or crystals can nucleate , the relative humidity can exceed 100%, in which case the air is said ...

In 2014, the state with the lowest fertility rate was Rhode Island, with a rate of 1.56, while Utah had the greatest rate with a rate of 2.33. [48] This correlates with the ages of the states' populations: Rhode Island has the ninth-oldest median age in the US – 39.2 – while Utah has the youngest – 29.0.
Volumetric water content, θ, is defined mathematically as: = where is the volume of water and = + + is equal to the total volume of the wet material, i.e. of the sum of the volume of solid host material (e.g., soil particles, vegetation tissue) , of water , and of air .
For example, the Pearson correlation coefficient is defined in terms of moments, and hence will be undefined if the moments are undefined. Measures of dependence based on quantiles are always defined.
Some argue that for a fair comparison, emissions should be analyzed in terms of the amount of CO 2 per capita. [12] Their main argument is illustrated by CO 2 per capita emissions in 2023, China's levels (9.24) are almost two thirds those of the United States (13.83) and less than a sixth of those of Palau (62.59 – the country with the ...
