900 mm is only 90 cm. The simplest way would be to insert a wooden rod (garden cane, broom handle, etc). Mark the ground level on the rod. Then measure the distance along the rod from the mark to the end with a tape measure.
No, a calorimeter is not designed to measure depth. It is a device used to measure the amount of heat released or absorbed in a chemical reaction or physical process. To measure the depth of something, you would typically need a different type of instrument, such as a ruler, tape measure, or a depth gauge.
No, a clinometer is not used to measure the depth of something. It is used to measure the angles of incline, slope, and elevation but not the actual depth.
there are many instruments used to measure length depending upon the size of object , Ruler is Metric instrument used to measure length. Screw gauge is also used as an instrument used to measure length in mm.
The barometer is the instrument that is used to measure the air pressure.
One instrument used to measure roughness of roads is the response type road roughness meters (RTRRMs)
A "depth gauge micrometer" is used by engineers. A depth gauge micrometer is a precision instrument used to measure various depths of different items.
No, a calorimeter is not designed to measure depth. It is a device used to measure the amount of heat released or absorbed in a chemical reaction or physical process. To measure the depth of something, you would typically need a different type of instrument, such as a ruler, tape measure, or a depth gauge.

No, a clinometer is not used to measure the depth of something. It is used to measure the angles of incline, slope, and elevation but not the actual depth.
fathometer is an instrument used to measure the altitude of na object above a fixed level , fathometer measures the sea depth
The instrument which is used to measure snowfall is called a snow gauge.
No. The instrument used to measure wind speed is an anemometer.
laparoscopy
A protractor is used to measure an angle.
A protractor can be used to measure an angle.
