# Welded Connections > Force on PP Fillet Welds (Angle to Plate)

# Notation and Units

## Metric and Imperial Units

The above welding stress equations may be used with both imperial and metric units. As with all mathematical calculations care must be taken to keep consistent units throughout. Examples of units which could be adopted have been provided below:

# Notation

- b = distance between welds, in or mm
- e
_{1}= distance from shear centre to weld, in or mm - e
_{2}= distance from shear centre to weld, in or mm - h = weld throat thickness, in or mm
- l
_{1}= length of weld, in or mm - l
_{2}= length of weld, in or mm - P = total axial force, kip or kN
- σ = stress in weld, psi or MPa
