10 Bar to Pounds per square inch (10 bar to psi)

Formula and worked answer

psi = bar × 14.5038

Substituting 10 for bar: 10 × 14.5038 = 145.038 psi. The factor 14.5038 comes from the exact international definition of the Bar relative to the Pound per square inch, so this answer is precise rather than rounded.

What does 10 Bar represent?

10 bar (145.04 psi) is a typical upper-end pressure for European track-cycling tubular tyres and a common reference on high-pressure metric floor pumps designed for time-trial and velodrome applications. Converted to imperial the figure is 145.04 psi, which sits just below the US "150 psi" round figure American track-cycling tyres often quote as their maximum sidewall pressure. The 4.96 psi gap matters in competition: a European track cyclist exporting their training equipment to a US event naively translating "10 bar" to "150 psi" by mistake over-inflates by about 5 psi, which is enough to elevate the rolling-resistance penalty and slow a 1 km TT effort by several tenths of a second against a precisely calibrated reference.
