Interval vs. Ratio

A distance in space.

A period of time.

Example: ‘the interval between contractions during childbirth’;

(music) The difference (a ratio or logarithmic measure) in pitch between two notes, often referring to those two pitches themselves (otherwise known as a dyad).

(mathematics) A connected section of the real line which may be empty or have a length of zero.

An intermission.

(sports) half time, a scheduled intermission between the periods of play

(cricket) Either of the two breaks, at lunch and tea, between the three sessions of a day's play

A space between things; a void space intervening between any two objects; as, an interval between two houses or hills.

Example: ‘'Twixt host and host but narrow space was left,A dreadful interval.’;

Space of time between any two points or events; as, the interval between the death of Charles I. of England, and the accession of Charles II.

A brief space of time between the recurrence of similar conditions or states; as, the interval between paroxysms of pain; intervals of sanity or delirium.

Difference in pitch between any two tones.

A tract of low ground between hills, or along the banks of a stream, usually alluvial land, enriched by the overflowings of the river, or by fertilizing deposits of earth from the adjacent hills. Cf. Bottom, n., 7.

Example: ‘The woody intervale just beyond the marshy land.’;

a definite length of time marked off by two instants

a set containing all points (or all real numbers) between two given endpoints

the distance between things;

Example: ‘fragile items require separation and cushioning’;

the difference in pitch between two notes

an intervening time

Example: ‘the day should be dry with sunny intervals’; ‘after his departure, there was an interval of many years without any meetings’;

a component of activity in interval training

Example: ‘they ran, sprinted, and jogged for four 15-minute intervals at two different times’;

a pause or break in activity

Example: ‘an interval of mourning’;

a period of time separating parts of a theatrical or musical performance.

a break between the parts of a sports match

Example: ‘United led 3–0 at the interval’;

a space between two things; a gap.

the difference in pitch between two sounds.

A number representing a comparison between two named things.

(arithmetic) The relative magnitudes of two quantities (usually expressed as a quotient).

(legal) Short for ratio decidendi.

The relation which one quantity or magnitude has to another of the same kind. It is expressed by the quotient of the division of the first by the second; thus, the ratio of 3 to 6 is expressed by

Hence, fixed relation of number, quantity, or degree; rate; proportion; as, the ratio of representation in Congress.

the relative magnitudes of two quantities (usually expressed as a quotient)

the quantitative relation between two amounts showing the number of times one value contains or is contained within the other

Example: ‘the ratio of men's jobs to women's is 8 to 1’;

In mathematics, a ratio indicates 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).
