What is the value of the roman numeral k?

Answer 1

The letter K is not used in Roman Numerals.

At one time the symbol K was one of several symbols which were used to represent the number 50 but the system was eventually standardised and L became the standard form for 50.

BETTER ANSWER;

K is not a Roman numeral. It is from our own alphabet and is actually

short for Kilo, which normally represents the 1000 multiple of a unit.

When we measure by mass, a kilogram is equal to 1000 grams. When the

letter K is used the way you gave in your example, 40K, it means:

40 x 1000 or 40,000 miles.

If you check the business or real estate section of your newspaper you

will see ads that say, for example, $130K. That means:

130 x 1000 or 130,000 dollars.

So "K" is a multiplier by 1000.
