Description: STP Calculator is an online tool for calculating Standard Temperature and Pressure easily. It takes the inputs and calculates the Standard Temperature and Pressure, so it is handy for solving problems requiring Standard Temperature and Pressure Calculations.
Formula: STP = Volume of gas x273TxP760
Example: Given parameters are,
Volume of the gas = 0.5L,
T = 300K,
P = 700 Torr
STP = Volume of gas x 273Tx P760
STP = 0.5 x 0.91 x 0.9210
STP = 0.4190L
With weight on other planets calculator you might check how much you’d weight if you landed on another planet within a Solar system.
One day we will be able to travel around Solar System just like we travel abroad now. What will change however (except travel costs and time!) will be our weight on particular planets. Depending where we land, we might weight only a small fraction of what we weight on Earth. Or if we choose to fly to Jupiter we might get depressed and consider ourselves suddenly well overweight. Those will be some exciting times.
Our calculator can help you quickly figure out how much would you weight on particular planets around Solar System (although Pluto is not considered a planet anymore, we included it here as we weight very very little over there). Just insert your weight in any unit and the tool will automatically return results for any other planet.
F = G * ((M * m) / r^2)
where F = gravitational forces,
G is Gravitational Constant,
M equals planet mass
while m is your mass and finally
r is planet radius.

Learn the relationship between wavelength and frequency with this wavelength calculator.The wavelength calculator can assist you in determining the relationship between frequency and wavelength. Continue reading if you are here to learn how to calculate frequency of a wave or look for the wavelength formula.
Wavelength (Lambda) = Wave Velocity (v) / Frequency (f)
λ = 10 / 100 = 0.1m
Use the velocity calculator to assess how fast an object moved, given a certain distances and time, in meters per second. Velocity Calculator is a kind of speed calculator which is based on the average velocity formula and enables you to estimate the speed of an object. When you know how to calculate velocity, you can work out the the speed you can achieve while walking, jogging, cycling or any other means of transport.

V = distance / time
V = 100 / 20 = 5 m/s
Ohm’s Law calculator let’s you explore the relationships between voltage, current, and resistance.relationships between voltage, current and resistance across a given conductor. Ohm’s Law formula and voltage formula are used mainly in electrical engineering and electronics. Knowing how to calculate power can be very helpful in the study of electronic circuits. All these calculations you can do with our Ohm Calculator.
In the rest of the article you’ll find:
- The Ohm’s Law formula
- How to use the voltage formula
- What the equation for power is
- How to calculate power
The voltage V in volts (V) is equal to the current I in amps (A) times the resistance R in ohms (Ω):
V(V) = I(A) × R(Ω)
The power P in watts (W) is equal to the voltage V in volts (V) times the current I in amps (A):
P(W) = V(V) × I(A)
P = 500 x 10 = 5000
R = V / I = 50
Kinetic energy calculator is a tool which helps you assess the energy of motion. It is based on the kinetic energy formula, which applies to every object which has vertical or horizontal motion.
The following part of the article will explain:
- What kinetic energy is
- How the kinetic energy formula is used
- The definition of kinetic energy
- What the difference between potential and kinetic energy is
KE = 1/2 (M * (V * V))
M = KE / (V * V)
V = KE / (1/2 * M)
KE = ½ (12 * (2 * 2) = 24
Einstein Mass Energy law states the principle that mass (m) and energy (E) are equivalent according to the equation E = mc2, where c is the velocity of light. When energy is removed from a system then mass is always removed along with the energy.
Einstein’s Law of Mass and Energy:
E = m × c2
m = E/c2
Speed of Light in a Vacuum:
c = √E/m
E: Energy, in J
m: Mass, in Kg
c: Speed of Light in a Vacuum, is 2.99792458 × 108 m/s
The minimum energy of light rays that pass in the vacuum is 3.6 m/s and the mass is 5.3 kg. Calculate the energy.
Step 1 :
Mass (m) = 5.3 Kg .
Energy (E) = ? J .
Speed of light in a vacuum = 3.6 m/s .
Step 2 :
Plug the values in the formula.
E = mc2 .
E = 5.3 * (3.6)2
E = 68.688 J
At sea level there is a pressure equivalent to 10 metres of water pressing down on all of us all the time. This is because of the weight of the air above us in the atmosphere. When you travel up a mountain, there is less air above you in the atmosphere,
The important effect of this decrease in pressure is this: in a given volume of air, there are fewer molecules present. This is really just another way of saying that the pressure is lower. (This is called Boyle’s law.) The percentage of those molecules that are oxygen is exactly the same: 21%. The problem is that there are fewer molecules of everything present, including oxygen.
P = P0 * exp (-g * M * (h-h0) / (R * T))
- h is the altitude at which we want to calculate the pressure, expressed in meters.
- P is the air pressure at altitude h.
- P0 is the pressure at the reference level h0. In our pressure calculator it is assumed that the reference level is located as sea level, so h0 = 0.
- T is the temperature at altitude h, expressed in Kelvins.
- g is the gravitational acceleration. For Earth, g = 9.80665 m/s^2.
- M is the molar mass of air. For Earthly air, M = 0.0289644 kg/mol.
- R is the universal gas constant. Its value is equal to R = 8.31432 N*m /(mol*K)
- Choose the altitude at which you want to calculate the atmospheric pressure – for example, 4000 m.
- Choose the reference pressure P0. A typical value for Earth is 1 atm, or 101 325 Pa.
- Determine the air temperature – for instance, 30°C.
- Type the data into the calculator (remember about correct units).
- You have just obtained the result – in our example, the air pressure at altitude 4000 m is equal to 64557.76 Pa.
Acceleration calculator is a tool that helps you to find out how fast the speed of an object is changing. It can work it out either based on a difference of velocities at two different points in time or based on mass of the accelerating object and the force that acts on it. If you’re asking yourself what is acceleration, what is the acceleration formula or what are the units of acceleration, keep reading and you’ll find out how to find acceleration.
Acceleration(a) = (v−u) / t
Where, a = Acceleration in m/s2
t = time in seconds
v = Final Velocity in m/s
u = Initial Velocity in m/s.
Determine the final velocity of the car, if it starts from rest and accelerates 4.3 m/s2 after 34.8 seconds?
Step 1 :
Initial Velocity(u) = 0 m/s
Final Velocity(v) = ?
Time(t) = 34.8 sec
Acceleration of the car = 4.3 m/s2
Step 2 :
Final Velocity(v) = u + at
v = (0 m/s) + (4.3 m/s2)*(34.8 sec)
v = 149.64 m/s
Final Velocity(v) = 149.64 m/s
