» How much helium do I need for my weather balloon? «

The weather balloon should burst at a certain altitude or rise with a certain speed, for example, to reduce the distance between the start and landing point? How much helium do I have to fill in the weather balloon?

With our helium calculator these questions can be answered. In addition to the weather balloon which is used, the helium calculator takes into account the attached payload and calculates exactly how much helium is needed so that the weather balloon bursts at a specific altitude. Alternatively, the helium calculator from Stratoflights calculates how much helium is needed to send the weather balloon to the stratosphere at the desired climb rate.


Burst Altitude:NaN
Ascent Rate:NaN
Time to Burst:NaN
Neck Lift:NaN
Volume:NaN If you use one NaNL gas bottle with 200 bar filling pressure:
The results calculated with the helium calculator are only approximate values and may deviate from reality due to the influence of other parameters and therefore do not provide a 100% guarantee of accuracy.
