A user seeks a chart for dimensions in the MLtT and FLtT systems, along with SI and English units, but struggles to find this information online. The website efunda.com is mentioned as a potential resource, though there is confusion about whether it charges fees for access. Other users clarify that efunda.com is free to browse, but some sections may require membership. Suggestions for alternative resources include EngNet and a project site for unit conversions. The discussion highlights the difficulty in finding specific dimensional expressions, particularly for terms like "Modulus of Elasticity" in the MLtT system.
