Waterless urinals can save between 15,000 and 45,000 US gallons (57,000 and 170,000 L) of water per urinal per year, depending on the amount of water used in the water-flushed urinal for comparison purposes, and the number of uses per day. For example, these numbers assume that the urinal would be used between 40 and 120 times per business day. [4]
Recurring expenditure costs are between US$1.5 and $4 per person per year for a traditional pit latrine, and up to three times higher for a pour flush pit latrine (without the costs of emptying). [5] As of 2013 pit latrines are used by an estimated 1.77 billion people, mostly in developing countries. [6]
The current practice for arranging toilets in public space, to allocate an equal surface area for males (seated toilets and urinals) and for females (seated toilets only), is a source of inequality because females require more time in the restroom than males and the less space occupied by urinals makes it possible to increase the number of ...
The requirement to use a cubicle rather than a urinal means urination takes longer and hand washing must be done more thoroughly. [ 3 ] [ 4 ] Females also make more visits to washrooms. Urinary tract infections and incontinence are more common in females. [ 3 ]

A public toilet, restroom, bathroom or washroom is a room or small building with toilets (or urinals) and sinks for use by the general public.
The siriometer is an obsolete astronomical measure equal to one million astronomical units, i.e., one million times the average distance between the Sun and Earth. [13] This distance is equal to about 15.8 light-years, 149.6 Pm, or 4.8 parsecs, and is about twice the distance from Earth to the star Sirius. [14]
gravity models, distance decay and other models of spatial interaction are based on the tendency of the volume of interaction between two locations to decrease as the distance between them increases due to the friction of distance, often in a pattern that is analogous (mathematically, not physically) to the Inverse-square law of many of the ...
In statistics, Cohen's h, popularized by Jacob Cohen, is a measure of distance between two proportions or probabilities. Cohen's h has several related uses: It can be used to describe the difference between two proportions as "small", "medium", or "large". It can be used to determine if the difference between two proportions is "meaningful".
