To measure an Allen key, use a caliper or a ruler to determine the width of the hexagonal opening at the end of the key. Common sizes are typically measured in millimeters or inches, depending on the system used. You can also compare the Allen key with a standard size chart to identify its size. Ensure to measure the key's width across the flat sides of the hexagon for accuracy.
I would use inches or centimeters, or millimeters to measure this.
Measure they key, typically found near one of the corners. And then measure it and see how many kilometers/miles it is then measure the distance from your starting point to finishing point and compare it to the key
Place a key in a measured amount of water, an the amount of water it displaces is an amount equal to the volume of the key.
You would use millimeters (mm) to measure the thickness of a house key, as it is a small unit appropriate for measuring such dimensions.
Probably Centimeters
If the piece is in the key of Eb (three flats in the key signature) then all E's in the piece are flat unless marked otherwise. All of the B's and A's in the piece are flat, too. If there's no Eb in the key signature, the marked Eb is just for that measure, unless cancelled or continued in the next measure (either would be marked).
To calculate the density of an irregular shaped object like a key, you would first measure its mass using a scale. Next, you would measure its volume using a displacement method with water. Finally, you would divide the mass of the key by its volume to determine the density.
do you mean kilograms? if so: 120lbs = 54.5 kgs (kilometer is a measure of distance whereas kilograms is a measure of weight).
About the same size as your backspace key. I didnt measure mine :-) sorry
It explains what a specific symbol or color means and how to measure distance on that map.
That depends what aspect of the car you want to measure: for example its length, volume, mass, weight, color, etc.
