Time & Rate Unit Conversion Function

Designed to supplement the conversion functions found in the aerospace toolbox (aerospace toolbox not required), CONVTIME handles time and rate units from nanosecond to millennium and per nanosecond to per millennium.

Unlike the aerospace toolbox functions, it is not necessary to specify output units, as CONVTIME will by default convert to the SI seconds or per second.

Allowable UI and UO strings (not case sensitive):
'ns'
'us','µs'
'ms'
's','sec'
'm','min'
'h','hr','hour'
'd','day'
'wk','week'
'y','yr','year'
'dec','decade'
'cent','century'
'millen','millennium'

Examples included in help:

Convert a matrix of time values from years to hours:
out = convtime([1 3; 4 5], 'year', 'hr')

Convert flow rate 0.2 gallons/second to gallons/day:
out = convtime(0.2, '/s', '/day')

Convert fuel burn rate 5000 lbm/hour to kg/s using aerospace toolbox:
out = convtime( convmass(5000, 'lbm', 'kg'), '/hour', '/s' )

If manufacturing 800 items per hour, find how many seconds are required to manufacture an item (convert 800 items/hour to seconds/item):
out = convtime(800, '/h', 's')

If 65 seconds elapse between mile markers on the highway, find the speed in miles/hour:
speed = convtime(65, 'sec', '/hour')
