How to convert calories to joules?

Calorie is a unit of energy, which is still widely used in nutrition measurement and fitness manual. The international standard energy unit is Joule
Kcal, also known as capital letter C, is most commonly used in food labeling. It is equivalent to the energy required to raise 1 kg of water at 15 ℃ for one degree under a standard atmospheric pressure. 1 kcal = 4.185 joules
Small card, also recorded as cal, is more seen in scientific research documents, 1000 small card = 1 large card
What is the conversion unit between pound and kilogram?
Please write more if possible,
Weight unit: 1 ounces = 437.5 grains = 28.350 grams, 1 pound = 16 ounces = 0.4536 kg, 1 u.s.t. = 100 pounds = 45.359 kg, 1 u.s.t. = 112 pounds = 50.802 kg, 1 u.s.t. = 2000 pounds = 0.9072 metric tons, 1 u.s.t. = 2240 pounds = 1.0161 metric tons
How to convert pound units
How many jin is a pound in a unit of weight
According to the international measurement conversion standard, 1 pound = 453.6 grams, and 1 jin = 500 grams, so 1 pound = 0.972 Jin
What is the English symbol of weight unit
Kg kg kilogram

The three most commonly used complex numbers are - S~
Given that the molar mass of a substance is m, the density is p, and the Avogadro constant is Na, what is the molecular volume V0 of the substance?
Is it V0 = m / (PNA)
If it is a solid or a liquid, it can be done basically. If it is a gas, it can not. The gas molecules have a large distance. The calculated V0 is the range of gas molecules moving in space, not the volume of gas molecules
It can be. It depends on what the material is. If it is a gas, its volume is very small, and the gap has reached the main position.
Yes, but pay attention to the unit
The formula for calculating the original cross-sectional area of the tube specimen, and the meaning and unit of each symbol?
S = π (R & # 178; - R & # 178;), R is the radius of large circle, R is the radius of small circle
In a series circuit, u = 10V, R1 = 2 ohm, R2 = 4 ohm, how much W is the electric power of R1 and R2
I = u / (R1 + R2) = 10 / (2 + 4) = 5 / 3 (a) 2. P_ R1=I*I*R1=(5/3)*(5/3)*2=50/9 (W)3.P_ R2 = I * I * R2 = (5 / 3) * (5 / 3) * 4 = 100 / 9 (W) finished
I=U/(R1+R2)=5/3 A
P1=I^2*R1==50/9 W
P2=I^2*R2==100/9 W
