For example, by using a positive pressure sensor, the analog voltage output is 1-5V. What is the analog current? I need to find an analog current of 4-20mA. What is the corresponding voltage?
This can't be compared. If the sensor output is current, it can only guarantee that the current value is linear to the measured value, and that the voltage will vary with the load, and so will the voltage product.
This does not depend on the conversion formula, but by the hardware circuit. The output signal is what you need to buy what kind of sensor output signal. If you want to change it to 4-20mA 1-5V on a 250 ohm resistor (if the driving load can add a voltage follower) can fix. 4-20mA and 1-5V turn to complex current circuit some.

An electric measuring instrument in a pressure measuring instrument is usually referred to as a pressure sensor. Pressure sensors are generally composed of an elastic sensitive element and a displacement sensitive element (or strain gauge). The elastic sensing element acts as a measure of pressure acting on an area and converts it to displacement or strain, and then converts the displacement sensitive element or a strain gauge into an electrical signal that is related to pressure. Sometimes the functions of these two components are integrated into one. Pressure sensors are widely used in various industrial automation environment, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military, petrochemical, oil, electric power, shipbuilding, machine tools, plumbing and other industries.
