Add abbreviation "h" for 100 in number boxes, like "k" for 1000

[NotRexButCaesar]

Currently, abbreviations for various numbers are "k" for 1000, "M" for 1000000, and "G" for 1000000000. These can be used when setting circuit network or other number box values for quicker typing. I propose the addition of the abbreviation "h" for 100. I commonly type the number 100, & it would be faster to type h instead.

Additionally, the prefix h exists in the game already when specifying planet pressure, which is measured in hPa.
