Bar to PSI Converter
psi = bar × 14.50377. 1 bar = 10⁵ Pa.
One bar is 100,000 Pa, about 14.50 psi — almost one atmosphere (14.70). European tire pumps in bar: 2.2 bar is 31.9 psi. SCUBA and espresso machines live here too. Close to atm, not the same.

- Atmospheres to PascalsStandard atmosphere is 101,325 Pa by definition. Chemistry problems still say “2 atm.” Multiply. 2 atm is 202,650 Pa or 2.026 bar. Weather “1013 mbar” is about 1 atm, not exactly unless you like rounding.
- Centimeters to Pixelspx = (cm / 2.54) × DPI. A 10 cm bar at 300 DPI is 1,181 px. A4 width 21 cm at 300 DPI is 2,480 px. Packaging die-lines still want millimeters and bleed; this is the raster step.
- Hectopascals to PascalsWeather: 1 hPa = 100 Pa = 1 millibar. Standard sea-level 1013.25 hPa is 101,325 Pa. A 850 hPa pressure surface is 85,000 Pa. METAR “Q1013” is this unit.
- Mebibytes to Megabytes1 MiB = 1,048,576 bytes. 1 MB = 1,000,000 bytes. Multiply MiB by 1.048576. A 700 MiB ISO is 734 MB on a decimal progress bar. That is why two windows never match.
- Pascals to PSIDivide pascals by 6,894.76. Atmospheric pressure 101,325 Pa is 14.70 psi. Tire stickers in kPa: 220 kPa is 220,000 Pa ≈ 31.9 psi. Do not put 220 in this box and call it 220 Pa.
- Pounds to KilogramsUS body weight and barbell math into the kg plates the rest of the gym already uses. Divide pounds by 2.20462. 150 lb is 68.0 kg, not “70 kg unless you are rounding for a form.”

A 5K is 5,000 meters, not 5 kilometers on the nose if your watch is sloppy. Divide meters by 1,000. Track races, building plans, and “how far was that hike” all live in this split.
Feet to Meters
Unit Converters
US height, ceiling height, and lumber still arrive in feet. Meter plans do not. One foot is exactly 0.3048 m — not “about a third.” Use this when a listing says 10 ft ceilings and the architect works in meters.
Inches to Centimeters
Unit Converters
Monitor diagonals, waist measurements, and photo prints still come in inches. Clothing charts in Europe come in cm. Multiply inches by 2.54. That factor is exact, not a kitchen guess.
