Torr to Pascals (torr to Pa)

Formula

1 torr = 133.322 Pa

pascals = torr × 133.3223684 — reverse: torr = pascals × 0.007500616827

The factor is derived from the SI definitions of both units (base unit: Pa) as listed in NIST SP 811; results on this page are shown to 6 significant figures, the API returns up to 12.

Worked examples

• 5 torr = 666.612 Pa
• 12.5 torr = 1666.53 Pa
• 100 torr = 13332.2 Pa
