• atmospheres: Standard atmosphere is 101,325 Pa (average sea-level pressure). In the ocean, pressure rises ~1 atm every 10 m.
• psi: psi (lb/in²) is the imperial pressure unit. US tires run ~30–35 psi; bike tires often 80–120 psi.
1 atm = 14.6959 psi. Use the converter above to compute any value, or multiply atm by 14.6959.
Yes — conversions use the standard international factors and are rounded to 4 decimals.
Atmospheres are used in chemistry, diving, and high-altitude pressure. psi is used for US tires, bikes, and compressors. Whenever a value is given in atm but you need psi, this converter is the quick fix.
