About these units
Thousand (k)
One thousand (10³).
Thousand traces back through Middle English thousend to Old English þūsend and a Proto-Germanic form, and it has close relatives across the Germanic languages: German tausend, Dutch duizend, Swedish tusen, and Icelandic þúsund. Cognates also appear in Slavic and Baltic languages, among them Polish tysiąc and Lithuanian tūkstantis. Learned English vocabulary adds chiliad, a collective for a thousand, and millennium.
Its Roman numeral is M, and its scientific shorthand is the SI prefix kilo-, standing for 10³. The word has not always meant 1,000. In Old Norse counting, which grouped numbers in twelves of tens, a thousand meant 1,200. At ordinary scales, a thousand seconds is about 16.7 minutes, and a thousand days is about 2.7 years.
1 thousand = 1,000 pieces (exactly).

Pair (pr)
Two items.
Pair comes from Old French paire, which grew out of Latin paria, the neuter plural of par, meaning equal. German Paar and Dutch paar are relatives of the same word. The core idea is two matching things taken together, as in a pair of shoes or gloves.
English also uses pair for single objects built from two connected parts. Scissors, spectacles, trousers, and jeans are plural-only nouns, so a counting word is needed: you say a pair of scissors or several pairs of jeans. That makes the unit slightly slippery. Six pairs of socks is 12 socks, but six pairs of scissors is only six objects. The word has other senses too, such as two people in a relationship or two cards of equal rank in poker, but as a quantity of loose items it is always two.
1 pair = 2 pieces (exactly).
