You would not put in "hours" or "hrs" then to qualify "15:32"?

Why complicate it... one typically knows what it mean from the
context in which it is used.

Depends on how you define "most people".

The majority of the people in a civilian supermarket, shopping mall or
movie theater.

Start asking people at random after noon what time it is.

How many respond in 24 hour time?

You may be right as long as you stick to your island :-)

The "rest of the world" uses 24 hours time :-)

1816 hrs = 75 days and 16 hours.
18:16 = 1 + 1 / 8, so this needs correction - although it is common on
digital watches.
18.16 = 18 + 16 / 100, so this is not true.
18-16 = 2.
What about
18 hours 16 minutes 38 seconds, and shortened
18 h 16 min 38 sec, or oldfashioned
18 h ( but the "h" put in upper case) 16 ' 38 ''
?

Typical... Five minutes in error.
18:11 hr

They do not pay attention to detail.
This is a more serious and costly trawl by the worst troll:

In France railway timetables etc put an 'h' after the hours figure so
11 minutes past six in the evening is written 18h11 and pronounced
"dix-huit heures onze"

I want to leave out the seconds. Also note that I am NOT referring
to computer conventions of any sort.

Where did your 16 come from??

Does it vary between being written by a word processor and by hand?
See below.

(2) What is the correct way to write a decimal point? I am English
and that means that a comma is not the correct symbol for the decomal
point.


Broaden your mind.

In Engalnd we use a dot as the conventional decimal 'point' or poinr where the integer numbers end. On the Continent they conventionally (in some countries) use a comma.


Another fact is we tend to use the 'x' as the abscissa in England, and the 'y' for the ordinate. This is reversed in some countries on the continent.


The fundamental thing to do is to learn to understand what concept you are looking at or reading of, then the convention does not matter provided you can follow through the logic in terms of the convention the authore has used.


But ISTR that when the decimal point was written by hand it was in
the air about half the height of the digits. Typewriters and word
prorcessors did not offer that half-way character so a full stop was
used. But is it more correct to handwrite the decimal point as half
way up the height of the digits?



In maths we have a two fold use of the point.

It can be on the line or half way up and either way it indicates the integer stop point.

A dot can also indicate the arithmetical function ususally written as a 'x', multiplictaion.


The sexagesimal system of recording time, with 3'30''32


followed by a 'o' superscript, would read as 3hrs and 30 minutes 32 seconds AM. The same thing is indicated by 3:30:32, or by 03:30:32.


To translate it to decimal you divide the minutes by sixty, and the seconds by 3600 and add the results to the hours.

e.g. 3:30:32 = 3+(30/60)+(32/3600) = 3.509


In the 12 hour format the AM or PM should be used to indicate ante or post meridian. In the 24 hour format this is not necessary as the tme progress to the 13th hour etc. when the 1st hour post meridian is hit. In this case midnight is wrotten as 00:00:00.

24 hour time is not relevant at all to most people.

For those that it is, I gave you the convention.

For a time to be meaningful to geographically separated people, you
also need to account for time zones. Those too confuse "layman".


Here in Europe we use 24 hour time a great deal.

Laymen and even old ladies both use it.

If you make a contention that applies only to the US then that's ok
but that is not where I live.
