Units in Trieres Config files.

Introduction

In each of the configuration files used in the 'trieres' game, numbers are entered in 'SI' units - meters, seconds, kilogrammes. Angles are in degrees and fractional quantities are entered as a number in the range 0.0 to 1.0.

However, when entering data from historical sources, it is often convenient to use alternative units. Trieres supports this - allowing numbers in configuration files to be followed by any of:

% -- Percentage
g -- Accelleration-due-to-Gravity
" -- Inches
' -- Feet
in" -- Inches
ft" -- Feet
yd" -- Yards
km -- Kilometers
m -- Meters
cm -- Centimeters
mm -- Millimeters
mi -- Miles
nm -- NauticalMiles
nmi -- NauticalMiles
kt -- Knots (Nautical Miles per hour)
knot -- Knots (Nautical Miles per hour)
m/s -- Meters per second
in/s -- Inches per second
fps -- Feet per second
kph -- Kilometers per hour
mph -- Miles per hour
s -- Seconds (time)
sec -- Seconds (time)
min -- Minutes (time)
hr -- Hours
hour -- Hours
dy -- Days
day -- Days
deg -- Degrees
deg/s -- Degrees per second

eg:


   10"       -- Ten inches
   10'       -- Ten feet
   10        -- Ten meters
   10m       -- Ten meters
   10.0nm    -- Ten nautical miles.
   10.0mi    -- Ten miles.

   0.0g      -- One tenth the accelleration due to gravity.
