SURVO MM Help System (web edition)

As an extension of editorial computing, various numerical conversions
may be performed by activating expressions like
        <number_or_word>(<unit1>:<unit2>)=_

For example, 440(yard:meter)=402.336 gives 440 yards as 402.336 meters.

In place of <number_or_word>, no composite expressions are accepted.
If <number_or_word> is missing, '1' is used as default.
For example, 1(yard:meter)=0.9144  (yard:meter)=0.9144

Multiple activations occur along the rules of editorial computing
by using '.=' instead of '='. For example,
   (ton:kg).=_     (pound:kg).=                  (pound:ounce).=
gives
   (ton:kg).=1000  (pound:kg).=0.45358541666624  (pound:ounce).=16

If a conversion between unsuitable units like (kg:m)=  is attempted,
an error message 'Conversion from kg to m is impossible!' is displayed.

When appropriate, the prefixes of the International System like
'mega' and 'micro' are recognized. Examples: (megaton:ton)=1000000
(nanometer:Ångström)=1 (femtosecond:sec)=1e-015

The data base for units of measurement is the edit field MEASURES.EDT
in the \SYS subdirectory of Survo. This field lists the possible units
with pertinent information in alphabetic order. The user can edit this
field by following instructions given in the same edit field.
