Convert Sonoff Zigbee Smart Water Valve flow from m3/hr to Liters/hr

Greetings… How do I create a new sensor from (sensor.sonoff_valve_flow) which shows the flow in M3/hr to Liters/hr ? Appreciate the assistance.

create a new template sensor and in the template you multiply the m3 value by 1000

template:
  - sensor:
      - name: "Some name"
        unit_of_measurement: "Liters/hr"
        state: "{[ states('sensor.sonoff_valve_flow') | float * 1000 }}"
