A handy app to convert between pressure units. Supported pressure units: • Atmosphere • Millibar • Bar • Pascal • Hectopascal • Kilopascal • Pounds per square inch (PSI) • Pounds per square foot (PSF) • Kilograms per square meter kgf/m² • Inches of mercury (inHg) • Millimeters of mercury (mmHg) • Torr "Flip" button to easily switch between the "from" and "to" units. Supports fractions. Results are shown in the decimal and fractional forms. App's Settings: - Rounding to the specified number of decimal places: for decimal numbers, you can select the number of decimal places you want to display. By default, the app displays 2 decimal places. To round results to the nearest whole number, select 0 decimal places. - For fractions, you can select rounding to the nearest 1/2, 1/4, 1/8, 1/16, 1/32, 1/64, 1/128, 1/256. By default, the app rounds fractions to the nearest 1/32. If you do not need to round fractions, just select "-". Sends results and history via email. Conversion history. Supports both portrait and landscape orientation.

Verdict
The clearest difference is update cadence: Pressure Unit Converter at every 2 months against Thermal Engineering Calc's every 15 months. Pressure Unit Converter also leads on rating (5.0 vs 4.7) and review sentiment (67% vs 50%). Thermal Engineering Calc's advantage is ratings volume (6 vs 1) and price ($2.99 vs $3.99). On ads, in-app purchases, monetization model and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Thermal Engineering Calc costs $2.99 and Pressure Unit Converter $3.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Pressure Unit Converter holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Thermal Engineering Calc has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 50% of Thermal Engineering Calc's written reviews are positive against 67% of Pressure Unit Converter's.
Thermal Engineering Calc ships an update every 15 months, Pressure Unit Converter every 2 months. The most recent releases landed on October 23, 2026 and October 24, 2026 respectively.
