PSI to Feet of Head Calculator

Use this calculator to convert PSI to feet of head and feet of head to PSI for pump sizing, boiler feed applications, condensate return systems, and general water movement calculations.

This conversion is commonly used when matching a replacement pump, checking required system pressure, or reviewing head requirements on commercial and industrial water systems.

Quick Reference
1 PSI = 2.31 Ft. Head
10 PSI = 23.1 ft
20 PSI = 46.2 ft
30 PSI = 69.3 ft
50 PSI = 115.5 ft

How to Use This for Pump Selection

Feet of head is one of the main numbers used to match a pump to a system. After converting pressure to head, compare that result with the required flow rate and the pump curve for the pump you are considering.

If you are matching a replacement pump, the converted head value helps narrow down the correct Burks pump series.

Where This Comes Up

  • Boiler feed pump sizing
  • Condensate return pump matching
  • Circulating pump replacement
  • Checking lift or pressure requirements
  • Reviewing system pressure against pump capability

What to Do After You Convert

Replacing a Pump?

Use your head number and flow requirement to narrow down the right replacement pump.

Browse Burks Pump Series

Replacing a Full Unit?

If the system includes a receiver tank, controls, and pump package, review full boiler feed and condensate return systems.

Need Tank-Only Replacement?

If the pump stays but the receiver is worn or leaking, review replacement tank options.

Need Help Matching by Head and Flow?

If you know your PSI, required feet of head, or approximate boiler size but are not sure which pump or system fits, send the model number, application, and available system information to info@remausa.com.

This page is a conversion tool. Final pump selection still depends on flow, head, system layout, voltage, and application type.
