Well kind of in lbs - this piece of wiki should make it all clear - as MUD

"The

**pound of force** or

**pound-force** (symbol:

**lbf**[1], sometimes

**lbf**,

[2]) is a

unit of

force or

weight used in some

systems of measurement including

English Engineering units
[a] and the

Foot–pound–second system.

[3] Pound-force should not be confused with

foot-pound, a unit of energy, or

pound-foot, a unit of torque, that may be written as "lbf⋅ft"; nor should these be confused with

pound-mass (symbol: lb), often simply called

*pound,* which is a unit of

mass."

It like a Monty Python sketch - I recommend going metric on this one if you want to get closer to what is going on. Indeed the manufacturers use the SI (International System of Units)unit of force (Newton) as their primary statement of the engines capacity to do something useful..

JetCat P20-SX micro turbine for small model jets with a thrust of 24 Newton or 2,4 kg
**JetCat P20-SX Micro Turbine with 24 Newton ,5,25 Lbs ( 2,4 Kg) Thrust.**
What this means is that the engine above (P20-SX) will just barely hold a 5.25lb bag of potatoes off the ground, using a suitable system of frictionless bearings, pulley and weightless cable so that the engine is not supporting itself or its fuel etc.
