How to Convert kW to CV?
To calculate the conversion from kW to CV, simply multiply the kilowatt value by the standard market equivalence constant. This process is essential for aligning an electric generator’s capacity with an industrial motor’s power demand.
The need to convert kW to CV arose during the Industrial Revolution when James Watt needed to compare steam engines to horses. The metric system later standardized the horsepower (CV) in Europe to simplify understanding mechanical power in machines.
Today, this conversion links the electrical power consumed to the mechanical work performed by a motor. In technical contexts of infrastructure and energy security, knowing how many CV are in 1 kW prevents overloads and errors in machine coupling.
kW to CV Conversion Formula
To convert kW to CV, apply the constant 1.35962. The kW to CV formula is: Power (CV) = Power (kW) × 1.3596. It’s a simple mathematical calculation but fundamental for power engineering.
For example, if you have equipment rated at 50 kW and need to know its mechanical power, the calculation is 50 x 1.3596. The result indicates that this system delivers approximately 68 CV of power.
How Many kW in 1 CV?
The exact numerical equivalence defines that 1 CV corresponds to 0.7355 kW. This value is widely used daily to specify the energy input needed for electric motors.
Knowing how many CV are in 1 kW (approximately 1.36 CV) helps interpret international technical catalogs. This clarity ensures that companies like Tecnogera deliver generator sets perfectly compatible with the client’s load and demand across different projects.

We present a table for quick reference of common values found in energy projects. These data assist in making quick decisions during equipment rental planning.
| Power in kW | Power in CV (approximate) |
| 1 kW | 1.36 CV |
| 5 kW | 6.80 CV |
| 10 kW | 13.60 CV |
| 50 kW | 68.00 CV |
| 100 kW | 135.96 CV |
| 500 kW | 679.81 CV |
What is kW (Kilowatt)?
The KW (Kilowatt) is the standard unit of measurement for active electrical power, representing the actual work done by electricity in a system.
In our sector, kW is the unit used to measure the energy output of Tecnogera’s power generators. It indicates the equipment’s capacity to support lighting equipment, machines, and active security systems.
Unlike other measures, kW focuses on the energy effectively transformed into light, heat, or movement. It is the main data for calculating consumption and energy efficiency in industrial plants.
What is CV (Horsepower)?
The CV (horsepower) measures a motor’s ability to perform work over a given time, being a traditional unit of mechanical power.
In the context of generator sets, CV is used to measure the power of the diesel engine that drives the alternator. It’s the raw power that will be converted into electrical energy to power your operation.
While kW looks at electrical output, CV focuses on the thermal engine’s capacity. At Tecnogera, we select generators with suitable engines to ensure uninterrupted operation.
How to Convert Power from CV to kW
Often the reverse path is necessary, especially when the client’s motor is already specified. For this, we use the inverse kW/CV formula: Power (kW) = Power (CV) / 1.3596 (or multiplying by 0.7355).
If a motor has 100 CV, converting to kilowatts results in approximately 73.55 kW. This data is crucial for the technical team to size the correct generator to meet the specific and necessary load.
Understanding this inversion allows greater agility in communication between suppliers and clients. Thus, we ensure that the available mechanical power is sufficient for the intended electrical generation by the client.
What is the Difference Between CV and HP (Horsepower)?
The difference between CV and HP can cause some confusion, but it basically lies in the origin and reference value, with each following technical standards. CV (horsepower) follows the DIN – Deutsches Institut für Norming or German Institute for Standardization (European), while HP (Horsepower) follows the SAE – Society of Automotive Engineers standard (American).
Numerically, 1 HP is approximately equivalent to 1.014 CV, being slightly more powerful. In Brazil and most of Europe, CV is the norm, but HP is common in some imported equipment.
It’s important not to confuse the two when specifying large-scale projects. Errors in this distinction can cause undersizing of critical systems, affecting your company’s energy security.
Practical Applications of kW to CV Conversion
The kW to CV conversion is applied daily in various strategic sectors to ensure operational continuity. See where these calculations are most frequent:
- Generator sizing: alignment between the combustion engine (CV) and the electric alternator (kW).
- Industrial electric motors: defining wiring and circuit breakers based on the conversion of required mechanical force.
- Pumping systems: calculating the power to move water volumes over large heights or distances.
- Automotive industry: specifying the performance of heavy machinery and trucks used in construction.
How to Determine How Many CV an Electric Motor Has?
To identify the power of an electric motor, it is recommended to:
- Locate the metal identification plate affixed to the motor body. Manufacturers usually list the power in kW, CV, or HP.
- If the plate is illegible, consult the manufacturer’s technical manual with the equipment model.
- If only the kW value is available, apply the conversion by multiplying by 1.36 to obtain the horsepower.
In high-performance motors, efficiency should also be considered in the actual calculation. Tecnogera’s team of specialists assists clients and partners in technically reading these specifications to ensure the rental of the ideal equipment.
Why Do Some Technical Sheets Use kVA?
The kVA (Kilovolt-ampere) represents the apparent power, which is the sum of active power (kW) and reactive power. It indicates the total load the electrical system needs to support to function.
The technical reason is that generators and transformers must be sized by the total load, not just the useful one. kW is what does the work, but kVA defines the robustness of the components.
Understanding this difference prevents component overload failures. In energy security projects, the balance between kW, CV, and kVA ensures supply stability.
Why is This Conversion Vital for Motors and Generators?
Electric generators are integrated systems where a motor (measured in CV) drives an alternator (measured in kW). Without harmony between these powers, the system can experience severe failures or excessive consumption.
Understanding the conversion is the first step for the correct sizing of any temporary energy plant. An undersized motor will not have the strength to maintain electrical frequency under full load.
On the other hand, an oversized motor leads to fuel waste and unnecessary costs. Tecnogera uses these calculations daily to offer solutions that balance raw power and efficient electrical delivery.
How Does kW to CV Conversion Impact Sizing?
Energy sizing goes far beyond a simple mathematical conversion. It’s an engineering study that analyzes motor efficiency, power factor, and starting loads.
Electric motors require an energy peak at startup that can be several times their nominal power in CV. Ignoring this dynamic can lead to system shutdown when it’s most needed.
Technical precision at this stage ensures that the operation runs without unwanted interruptions. This is where standards analysis and field experience turn numbers into real operational safety.
