# Pst vs. Pct: What's the Difference?

By Aimie Carlson & Harlon Moss || Updated on May 21, 2024
Pst is shorthand for "past," often used informally to refer to a time before the present, whereas Pct stands for "percent," representing a part of a whole in hundredths.

## Key Differences

Pst is commonly used as an informal abbreviation for "past," which refers to a time that has already occurred. It’s often seen in casual writing or text messaging to quickly indicate events that happened before the present time. Pct, on the other hand, is an abbreviation for "percent," a term used in mathematics and statistics to denote a part of a whole expressed in hundredths. For instance, if you say 50 pct, you mean 50 out of 100 parts, or 50%.
When using Pst, it generally relates to time and events that have already happened. This abbreviation is typically less formal and more suited for informal contexts like notes, personal reminders, or casual conversations. Pct is used in more formal contexts involving data, statistics, or mathematical calculations. It is a standardized abbreviation found in academic, professional, and technical writing where precise measurements and proportions are essential.
Pst does not usually appear in professional or academic writing due to its informal nature, while Pct is widely accepted and understood in such contexts, ensuring clarity and accuracy in the presentation of numerical data.
Both Pst and Pct are abbreviated forms, but they serve entirely different purposes one is temporal, relating to time, and the other is numerical, relating to proportions.
