Direct and indirect measurement
Direct and indirect measurement Direct and indirect measurements include: 1. Direct Measurement is a measurement using a measuring instrument so that the measurement results can be obtained directly. For example: Measuring the circumference of a tree using a tape measure. 2. Indirect measurement is a measurement that requires a process of at least two steps to determine the measured results. For example: Measuring the circumference of a tree by wrapping a rope, then measuring the length of the rope with a ruler.
