| 1 Pa | = 10⁻⁶ N/mm² = 10⁻⁵ bar = 0.1020 kp/m² = 1.02×10⁻⁴ m H₂O = 9.869×10⁻⁶ atm = 1.45×10⁻⁴ psi |
| 1 kW | = 1,000 W = 3,412 Btu/h = 1.341 British hp |
| 1 liter/s | = 10⁻³ m³/s = 3.6 m³/h = 0.03532 ft³/s = 2.1189 ft³/min = 13.200 Imp.gal/min = 15.852 US gal/min |
| 1 m/s | = 3.6 km/h = 196.85 ft/min = 2.237 mph |
| 1 m | = 3.2808 ft = 39.37 in = 1.0936 yd |

Example Calculation
For a 2" BS 1387 steel hot water heating pipe with a heat flow of 100 kW and a temperature difference of 20 °C:
- Water Flow Rate: 1.2 liter/s
- Flow Velocity: 0.54 m/s
- Pressure Loss: 60 Pa/m
This example illustrates how to use the data and relationships presented in the pressure loss nomogram to estimate system parameters.
