This table shows thermal conductivity in SI units of watts per metre-kelvin (W·m −1 ·K −1). Some measurements use the imperial unit BTUs per foot per hour per degree Fahrenheit ( 1 BTU h −1 ft −1 F −1 = 1.728 W·m −1 ·K −1 ).
The specific power may be expressed in watts per kilogram of body mass. Active cyclists can produce from 1.0 W/kg (novice female) 2.2 W/kg (average untrained male), 3.0 W/kg (male, fair or female, good [fitness]), and 6.6 W/kg (top-class male athletes) at their functional threshold power (about one hour). 5 W/kg is about the level reachable by ...
The contribution of the muscle to the specific heat of the body is approximately 47%, and the contribution of the fat and skin is approximately 24%. The specific heat of tissues range from ~0.7 kJ · kg−1 · °C−1 for tooth (enamel) to 4.2 kJ · kg−1 · °C−1 for eye (sclera). [13]
Fix these common indoor cycling setup mistakes and you could be cranking out more power than you even knew you had.

The SI unit of absolute thermal resistance is kelvins per watt (K/W) or the equivalent degrees Celsius per watt (°C/W) – the two are the same since the intervals are equal: ΔT = 1 K = 1 °C. The thermal resistance of materials is of great interest to electronic engineers because most electrical components generate heat and need to be cooled.
The rate of heat flow is the amount of heat that is transferred per unit of time in some material, usually measured in watts (joules per second). Heat is the flow of thermal energy driven by thermal non-equilibrium, so the term 'heat flow' is a redundancy (i.e. a pleonasm). Heat must not be confused with stored thermal energy, and moving a hot ...
The SI unit of specific heat capacity is joule per kelvin per kilogram, J⋅kg −1 ⋅K −1. [2] For example, the heat required to raise the temperature of 1 kg of water by 1 K is 4184 joules, so the specific heat capacity of water is 4184 J⋅kg −1 ⋅K −1. [3]
