mõõtures
Mõõtures is a term that generally refers to a measuring instrument or device. In Estonian, "mõõt" means measure and "ures" is a suffix indicating an agent or tool. Therefore, a mõõtures is literally something that measures. This broad definition can encompass a wide variety of tools used for quantifying physical properties.
Examples of mõõtures include devices for measuring length, such as rulers (joonlaud) or measuring tapes (mõõdulint).
The specific type of mõõtures used depends entirely on the property being measured and the required precision.
