PRESSURE UNIT CONVERSIONS — DIMENSIONAL ANALYSIS TRAINER

Goal: learn conversions by making units cancel. Use the “DA Builder” until it feels automatic.
PART A — MEMORIZE THESE (THEY POWER ALL CONVERSIONS)
Standard pressure

1 atm = 101.325 kPa = 101,325 Pa

1 atm = 760 mm Hg = 760 torr

1 atm = 14.7 psi

Dimensional analysis = multiply by a fraction that equals 1 so the units cancel.

DA rule
  1. Write what you start with.
  2. Multiply by a conversion factor where the starting unit is on the bottom.
  3. Cancel units, then calculate.

If units don’t cancel, the fraction is upside down.

kPa ↔ Pa

1 kPa = 1000 Pa

This is the only non-atm fact you need.

PART B — DA BUILDER (BUILD THE FRACTION THAT CANCELS UNITS)
Practice Problem
Your job: choose the right conversion factor orientation.
Round: none
Step 1 — Choose your conversion factor
Pick the fraction so your starting unit is on the bottom and cancels.
Top value: --
Bottom value: --

Live Dimensional Analysis
Watch the unit cancel (or fail to cancel).

Notebook Notes (copy these headings)
  • Goal: make units cancel
  • Rule: starting unit must be in the denominator of the conversion factor
  • Strategy: if it’s not a direct match, convert to atm first, then to the target unit

When you finish: write your work in your notebook and take a screenshot of a solved example to upload to Google Classroom.

PART C — QUICK CHECKS (YOU SAY WHICH WAY THE FRACTION GOES)
Quick Check 1

To convert kPa → atm, the conversion factor should have:

--

Quick Check 2

To convert mm Hg → kPa, the conversion factor should have:

--
