Here are some examples:
* Length: Measured with a ruler, tape measure, or calipers.
* Mass: Measured with a balance scale or a digital scale.
* Volume: Measured with a graduated cylinder, beaker, or measuring cup.
* Temperature: Measured with a thermometer.
* Time: Measured with a clock, stopwatch, or timer.
* Current: Measured with an ammeter.
* Voltage: Measured with a voltmeter.
These are just a few examples, and there are many other quantities that can be measured directly with devices.
Important Note: Some quantities might be derived from directly measured values. For instance, speed is calculated from distance and time (both of which can be measured directly). While speed itself isn't directly measured, it relies on quantities that are.
