Why people convert Argentina to CLT time

Scheduling a call from Argentina to CLT: a 10:00 AM start in Argentina lands at 9:00 AM in CLT, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Argentina and CLT are inside the 9-to-5 working day between 10:00 AM and 5:00 PM ART time (9:00 AM–4:00 PM CLT). That is roughly 7 hours of usable overlap.
Coordinating a Argentina-based team with CLT contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.

Always state the zone abbreviation, not just the hour. "3:00 PM ART" is unambiguous; "3 PM" across a -1h gap is not.
Block 10:00 AM–5:00 PM ART as the recurring meeting window if you work primarily from Argentina and need CLT colleagues present.
