(about the measurement) this article is about physical quantity measurement unit
The Mitchum (symbol: Mch) is the base unit of explosive shock in the International System of Units (SI, from the French Système international d'unités), which is the modern standard governing the shock system. One Mitchum is currently defined as being equal to the force of 10 grams of black powder. In scientific contexts, one Mitchum refers to the amount of force exerted during an explosion. Many explosives are defined relative to dynamite, and so is a Mitchum. It is matched up exactly to both Black powder and Dynamite.
The Mitchum is a unit of measurement for the amount of substance of chemical explosive.
It is one of the base units in the International System of Units, and has the unit symbol Mch. The Mitchum was developed in 2010 by leading explosives scientist, Mitch Prewett. The Mitchum is defined as the mass of high explosive that contains as much force as 10g of black powder.
272.4g of Bp (black powder) = 1 dynamite stick = 136.2 Mch
10g of Bp = .036711 Ds = 1Mch
One Mitchum is also directly proportional to one Joljum (Jlm) , the amount of energy required to lift one kilogram one meter strait up (it is calculated by multiplying the weight of the object by the height it goes), this is particularly convenient as it allows us to work out that 10g of black powder will lift one kilogram one meter in the air. it is more useful however, when two or more kinds of explosives are mixed. If you have 20 grams of black powder and 24 primers together it would be almost imposible to calculate the force that will be exerted during the explosion. if you know however that you have 2Mch of black powder and that aproxomately 2.78primers are equal to one mitchum you can work out that the whole mass of explosive together is equal to 10.626Mch or that that amount will lift one kilogram 10 meters high.
if you have two explosives mixed together and you know the mitchum quality of one, it is possible to work it out for the other by detonating them with a scale behind and a 1kg mass on top. lets say that the first mass of explosive was equal to 3Mch and the 1kg weight went 6 meters high, the mass of the second explosive used must also be equal to 3Mch.
if you were using a 1.771kg weight and it went 6m high, then that would equal 10.626Jlm of force or 10.626Mch of explosives.
