A measuring cylinder
You don't really need to measure the water in a birdbath, just put some in a couple inches deep.
You need to do the water displacement method. The water displacement needs a graduated cylinder and water.
You need a scale to measure the weight and ways to submerge the block and measure the water to determine the volume.
The density of things that sink is greater than the density of water. In the metric system, this would be 1 gram per cm3, so the measure of the mass of the sinking object (in grams) should be greater than the measure of its volume (in cm3).
Litres is a measure of liquid volume. Grams is a measure of mass. You need to know the density of the matter , befire yiou can make a comparison.
you simply measure 15mls of bleach to 1 litre of water.

A graduated cylinder
You cannot directly associate weight and volume. You firstly need to know the shape and other dimensions in order to find the volume. Then you need to apply the density of the material, i.e. what it weighs per volume.
no its not but if you need to measure the volume of it you drop it in water and measure the amount of water displaced
Immerse the object in water and measure the volume of water that is displaced. One way would be to fill a container, large enough to hold the object, with water until it is just about to overflow. The container and water would need to be inside another container that could capture the displaced water. Submerge the object in the water and then measure the volume (or weight) of the water that overflows
We need to measure the electrical conductivity.
You would need a balance to measure its mass. You would need a ruler to measure the length of its sides. Then you would need to calculate volume. Then divide the mass by the volume to get density.
You can not measure the number of liters with just the weight of the bowl. You would need to know the size of it.
typically, acresMy VersionI measure a lake in surface area, Square Miles in my case, and Ice thickness for safety. As you can see my measurement is for my uses.You may measure the amount of water, the depth of the water, The cleanliness of the water, the height of the lake above sea level or dozens of other ways depending on what you need to know.

That depends on which property of the water you need to measure. -- Its temperature . . . degrees Celsius or Fahrenheit. -- Its volume . . . liter or fluid ounce. -- Its weight . . . Newton or pound. -- Its mass . . . kilogram or pound. -- Its conductivity . . . Siemens. -- Its depth . . . inch or centimeter. -- Its clarity or purity . . . I don't know units for either of those, but my only point is that you don't "measure water" . . . you measure its properties.
