density problem

There is water in the container. The top pressure gauge P1 reads 0.132MPA and the bottom pressure gauge reads 0.141MPA. Find the height H of the water in the container. (The density of water is 1.0T/cubic meter) Its formula is as follows: g(z2-z1)=P1-P2/density=0.141-0.132=0.009 H=0.009/9.81 * 10 minus 3 power = 0.917 (meter) I don’t know where the negative 3 power of 10 comes from. (Note: Since I couldn't find the relevant symbols, I had to use Chinese instead. )
When you are doing it, convert all the units into standard units, convert tons into kilograms, and convert megapascals into pascals, and you will know how the results come from. The above formula is mainly a matter of units.
