The calorie per second (cal/s) is a unit of power that measures the rate at which energy is expended or consumed. Specifically, it quantifies how many calories are used every second, making it a crucial metric in fields such as nutrition, exercise science, and thermodynamics. Understanding this unit is essential for those looking to manage their energy intake and expenditure effectively.
The calorie is a standardized unit of energy defined by the International System of Units (SI). One calorie is equivalent to the amount of energy required to raise the temperature of one gram of water by one degree Celsius. The calorie per second is derived from this definition, allowing for a clear understanding of energy consumption over time.
The concept of the calorie was first introduced in the early 19th century by French chemist Nicolas Clément. Over the years, the calorie has evolved into various forms, including the kilocalorie (kcal), which is commonly used in dietary contexts. The calorie per second has become increasingly relevant in modern health and fitness discussions, particularly with the rise of wearable technology that tracks energy expenditure.
To illustrate how to use the calorie per second unit, consider a person who burns 600 calories during a 30-minute workout. To find the rate in cal/s, divide the total calories burned by the duration in seconds:
600 calories / (30 minutes × 60 seconds) = 0.333 cal/s
This means the individual expended energy at a rate of 0.333 calories per second during their workout.
The calorie per second is particularly useful for athletes, fitness enthusiasts, and health professionals who need to monitor energy expenditure during physical activities. It can also be applied in scientific research to study metabolic rates and energy balance.

The volt-ampere (VA) is a unit of measurement used to express apparent power in an electrical circuit. It represents the product of voltage (in volts) and current (in amperes) in an AC (alternating current) system. Unlike watts, which measure real power, volt-amperes account for both active and reactive power, making them essential for understanding the performance of electrical systems.
The volt-ampere is standardized under the International System of Units (SI) and is widely recognized in electrical engineering. The symbol for volt-ampere is VA, and it is often used in conjunction with other units to describe the power capacity of electrical devices, such as transformers and generators.
The concept of apparent power, represented by the volt-ampere, emerged as electrical systems evolved in the late 19th century. As AC systems became prevalent, the need for a unit that could encompass both voltage and current became essential. The volt-ampere was introduced to provide a clear understanding of power in AC circuits, distinguishing it from direct current (DC) systems.
To calculate the apparent power in volt-amperes, simply multiply the voltage (V) by the current (I): [ \text{VA} = V \times I ] For example, if a circuit operates at 120 volts and draws 5 amperes, the apparent power would be: [ \text{VA} = 120 , V \times 5 , A = 600 , VA ]
Volt-amperes are crucial in various applications, including:
