deriving meters per tik from miles per hour

speed is a measure of distance per unit of time. the use of particular units for measuring distance and time is subject to conditions of practicable use and descriptive utility. for example a speed measured in miles per hour is defined by the number of miles traversed in one hour. the application of the measure is not however limited to concepts of mile and hour; and is independent in its application of whether or not an object is actually in motion for one hour. the rate can be applied as well to motions moving less than one mile and taking place in less than one hour.

a speed of 25 miles per hour is defined by concepts of mile and hour; however is probably understood by a city-area driver with reference to a system of speed limits and the use of a speedometer.

determining which decimally-related units of the Inter-Dial Clock (IDC) system might be practicable for measuring rates of speed calls for an examination of the units applicable to a general use of the system by which speed may be measured. a consideration of units for measuring vehicle speeds follows. the meter provides a basic practical measure of distance. the IDC main unit of time is equal to 1 day or 1 chron (Xn), however a tikochron (IDC 0.00001 Xn or tt010 is 0.864 seconds) may provide a measure that is easier to intuit in practical use. a comparison of miles per hour to meters per tik is made via the following conversions:


table 2092.1 ✧ determining IDC conversion factors

1 mile is 1.6093742 kilometers
1 kilometer is 1000 meters
1 chron is approximately 24 hours (coordinated measure)
1 chron is 100 000 tiks
1 tikochron is equal to 10 microchrons—1 tiXn = 10 μXn.
1 tikochron is equal to 10 microchrons—1 tiXn = 10 μXn.
1 meter solana (m·so) is an alternative representation of equal quanity of 1 meter per tik (m/tiXn)
1 meter solana (m·so) is approximately 2.588998051 miles per hour (mph)
1 meter solana (m·so) is approximately 4.166654531 kilometers per hour (km/h)
1 kilometer per hour (km/h) is approximately 0.240000699 meter solana (m·so)
1 mile per hour (mph) is approximately 0.386249808 meter solana (m·so)

consequently one arrives at the following practicable conversions:

comparison of meter solana scale

table 2092.2 shows a range of rates in terms of meter solana determined to two significant places. a walking pace of 1.5 meter solana is comparable to a rate of 6 kilometers or 4 miles per hour. other uniform values from 5 to 29 meter solana correspond to rates of 20 to 120 kilometers per hour or to rates of 5 to 75 miles per hour.

developers and users should consider that subjective measures of speeds (especially with reference to a local frame of reference such as a pedestrian or a traffic intersection) can be more practicably determined by a meter solana scale, as the component units of meter and tik can be more readily determined by a subjective user than the component units of hour with regard to kilometer or mile. likewise the fixed measure of speeds by speedometers or radars in terms of a meter solana scale may also provide users with data that is more clearly intuited and thus more readily meaningful.

the use of the kilometers per hour and miles per hour scales are more clearly intuited in terms of a frame of reference to long-distance travel, yet the units impose certain practical limits on the level of scalar precision applicable to other situations. in addition, numerical calculations of scale conversions among the fractionally-constrained hour, minute, and second units are cumbersome. the conversion of SMH units among other designated SMH units moreover usually results in values that are not decimally coherent.

these practical conditions further support an AAT review of the practicable accommodations offered by the use of a time scale that is coherent to a main unit of 1 fixed-day for any designated level of scalar precision. the meter solana scale is practicably related to a main time unit of 1 fixed-day and a distance unit of 1 meter, also facilitating practicable conversion to other units of distance and time that are decimally related to these units.

developers and users should also consider that issues of scale conversion can impose certain user tasks dependent upon the scale support available for primary and target scales. because the meter solana scale is derived via different methods than the kilometers per hour and the miles per hour scales, the conversion factors themselves are not uniform and thus not practicable for ready calculation by users. thus developers should consider that scale applications and methods should be determined with regard to a user focus on uniform and meaningful values in support of usable design. there is a strong rationale for pursuing the development of a system of usable design in terms of a scalar framework that is more readily intuitive and more precise, while also reducing demands for users to perform cumbersome calculations.

developers and users should consider that if appropriately implemented, that the uniform units of ICAS and SI may be highly practicable for new and emerging methods and applications. table 2092.3 also provides a comparison of the meter solana scale in terms of designated per hour rates:
