| \(\large{ \sigma_h }\) (Greek symbol sigma) = spherical hoop stress | \(\large{\frac{lbf}{in^2}}\) | \(\large{Pa}\) |
| \(\large{ p_e }\) = external pressure | \(\large{\frac{lbf}{in^2}}\) | \(\large{Pa}\) |
| \(\large{ r }\) = radius to point of intrest | \(\large{ in }\) | \(\large{ mm }\) |
| \(\large{ r_e }\) = external radius | \(\large{ in }\) | \(\large{ mm }\) |
| \(\large{ r_i }\) = internal radius | \(\large{ in }\) | \(\large{ mm }\) |
