| '''Thames Measurement''', also known as '''Thames Tonnage''', is a system for measuring ships and boats. It was created in 1855 by the [[Royal Thames Yacht Club]], and was designed for small vessels, such as [[yacht]]s. It was originally used for calculating the port dues for yachts; the formula was also used in some early [[handicapping]] systems for [[yacht racing]].<ref>[http://www.boatus.com/goodoldboat/ratingrules.htm ''Rating rules shaped our boats''], by Ted Brewer.

| The calculation of Thames Tonnage uses the following formula:
| |
| | |
| <center><math>{{Thames\ Tonnage}} = \frac {({length}-{beam}) \times {beam} \times \frac {beam}{2}} {94}</math></center>
| |
| | |
| where:
| |
| *''length'' is the length, in [[foot (length)|feet]], from the stempost to sternpost;
| |
| *''beam'' is the maximum [[beam (nautical)|beam]], in feet.
| |
| | |
| This can be simplified as:
| |
| | |
| <center><math>{{Thames\ Tonnage}} = \frac {({length}-{beam}) \times {beam}^2} {188}</math></center>
