At that time, metric restriction signs could only be used in combination with, and positioned below, an equivalent imperial sign.

For fun, here's an expanded version of the diagram, with a few more imperial units added, like cubic inches.

How many people know all the imperial conversion factors?

For anyone daunted by learning the metric system 📏, the equivalent #metric chart is included alongside.

The report noted:

"the serious loss of time incurred by English school children in having to learn the complicated system of tables of existing weights and measures.

... no less than one year’s school time would be saved if the metrical system were taught in place of that now in use." 🏫
