# How to calculate the autonomy of a UPS? ### How to calculate the autonomy of a UPS?

You want to run equipment (the load) with a power of 2000 watts for 6 hours. For the calculationstart by determining the current by dividing the load by the battery voltage: 2000/ A. Then, multiply the current by the time ofautonomy required: 200A x 6h = 1200Ah.

### How to calculate the power of a UPS?

– If the values ​​are expressed in Amperes, multiply by 230 to obtain VA (Example: 7, V = 1725 VA). o Indeed, the Powerful Apparent is the product of the voltage in Volts by the Intensity in Amps. – If the values ​​are expressed in Watts, divide by 0.7 to obtain VA.

### How to calculate battery life?

L’autonomy of one drums in kilometer is equal to its capacity in Wh divided by the consumption in Wh per kilometer. Manufacturers do not always indicate the capacity of the drums in Wh but this one is simple to calculate. For example a drums of 36 Volts 10 Ah has a capacity of 36 V x Wh.

### How to calculate the autonomy of a device?

The formula is: P = UI, i.e. I = P/U (in units, this gives: amps = watts/volts).

### How to convert VA to watts?

watts. electrical power = voltage x current. watt = volt x ampere or 1 watt = 1 volt x 1 ampere….The power of electrical appliances.

Type of electrical deviceAverage power in watts of an electrical deviceAverage consumption estimate
television1 W125 kWh

### How to calculate the power needed for an inverter?

The inverter power is expressed in VA, or Volt Amps….Number VA = Number of Watts /0.66

1. For 1 Classic PC: 200 Watt consumption i.e. 300 VA of Powerful.
2. For 1 Server PC: 250 Watt consumption i.e. 350 VA of Powerful.
3. For 1 Standard screen: 90 Watt consumption i.e. 150 VA of Powerful.

### How to calculate price per kilometer?

This technique consists of adding the fixed costs with the variable costs and the ancillary costs, then dividing the sum obtained by the number of kilometer carried out. The first sum is used to determine the total cost of transport.
