Frequently Asked Questions

What is the difference between a calorie and a Calorie?

A lowercase calorie (cal) is the energy to raise 1 gram of water by 1°C. An uppercase Calorie (Cal, or kilocalorie) is 1,000 calories and is what food labels use. When a food label says 200 Calories, it means 200 kilocalories.

How much energy does a kWh represent?

One kilowatt-hour (kWh) is 3.6 million joules. It is the energy consumed by a 1,000-watt appliance running for one hour. The average US household uses about 30 kWh per day.

What is standard atmospheric pressure?

Standard atmospheric pressure at sea level is 1 atmosphere (atm), which equals 101,325 pascals, 1.01325 bar, 14.696 PSI, or 760 mmHg.

What is PSI and where is it used?

PSI stands for Pounds per Square Inch. It is commonly used in the US for tire pressure (typically 30-35 PSI for cars), plumbing, and industrial applications.
