Ratio Inches per foot Millimetres per foot ... 1:1000: 0.305 mm This is a scale used in Germany for pre-finished airliner models. ... At 1 inch in this scale = 6 feet ...
The scale ratio of a model represents the proportional ratio of a linear dimension of the model to the same feature of the original. Examples include a 3-dimensional scale model of a building or the scale drawings of the elevations or plans of a building. [1] In such cases the scale is dimensionless and exact throughout the model or drawing.
A clean print at a typical movie theater may have a contrast ratio of 500:1, [8] a transmissive digital projector is around 200:1, and a reflective digital projector (i.e. DLP) is around 500:1 under nearly ideal circumstances. [9] [better source needed] A modern computer LCD monitor is typically at 1000:1, [10] and TVs might be over 4000:1. [11]
A graphical or bar scale. A map would also usually give its scale numerically ("1:50,000", for instance, means that one cm on the map represents 50,000cm of real space, which is 500 meters) A bar scale with the nominal scale expressed as "1:600 000", meaning 1 cm on the map corresponds to 600,000 cm=6 km on the ground.
The ratio improved to 1:28 ratio in late 2005, meaning one civilian killed for every 28 combatants. It lowered, however, to 1:10 in 2006. In 2007, the ratio was at its lowest ever, more than 1:30. [47] Figures showing an improvement from 1:1 in 2002 to 1:30 in 2008 were also cited by The Jerusalem Post journalist Yaakov Katz. [34]
A sex ratio is the ratio of males to females in a population. As explained by Fisher's principle, for evolutionary reasons this is typically about 1:1 in species which reproduce sexually. [ 2][ 3] However, many species deviate from an even sex ratio, either periodically or permanently. Examples include parthenogenic species, periodically mating ...
In mathematics, a ratio ( / ˈreɪʃ ( i) oʊ /) shows how many times one number contains another. For example, if there are eight oranges and six lemons in a bowl of fruit, then the ratio of oranges to lemons is eight to six (that is, 8:6, which is equivalent to the ratio 4:3). Similarly, the ratio of lemons to oranges is 6:8 (or 3:4) and the ...
A thermal mass flow meter has a turndown ratio of 1000:1. An orifice plate meter has a practical turndown ratio of 3:1. A turbine meter has a turndown ratio of 10:1. Rotary positive displacement meters have a turndown ratio of between 10:1 and 80:1, depending on the manufacturer and the application.
