Capital K or lower case k for thousand?

Answer 1

The convention in the metric system is to use a lowercase "k" to represent a thousand. For example, 1 kilometer (1 km) is equal to 1000 meters. In contrast, capital "K" is generally used to represent Kelvin, the unit of temperature in the International System of Units.

Answer 2

Well, honey, when we're talking about representing thousand, we use a capital "K." It's like shouting from the rooftops, "I've got a thousand of these bad boys!" So, go big or go home with that capital "K."

Answer 3

Lower case k means 1000, 10kg for 10 kilograms. 10km for 10 kilometres. A 10K run is informal usage, but is understood by most people. Officially, uppercase K refers to temperature and means Kelvin.

Answer 4

Lower Case k means 1000, upper case K is meaningless.
