Compound measures

Compound measures is a theme within connecting measurement and decimals. Links to relevant activities and resources are on the right hand side of this page. 

Compound measures are ones that involve two other measures of different types; examples include measuring speed in metres per second, or defining density as mass divided by volume. Further categories of measure include non-linear measures (such as measuring sound intensity in decibels) and what are sometimes called derived measures (such as measuring inter-stellar distances in measure in light years).
