Convert Milliwatt to BTU per Second

Type the number of milliwatts that you wish to convert to btu per second.

1 mW (milliwatts) = 947.81712031 BTU/s (btu per second)

How to Convert Milliwatts to BTU per Second

The milliwatt and btu per second are both units of power. 1 milliwatt equals 947.81712031 btu per second. This means to convert milliwatts to btu per second, you multiply by 947.81712031.

Formula

btu per second = milliwatts × 947.81712031

Step-by-Step Example

Convert 5 mW to btu per second:

1
Convert 5 mW to btu per second

We need to convert milliwatts to btu per second

2
Apply the formula

Since 1 mW = 947.81712031 BTU/s, multiply by 947.81712031

5 × 947.81712031 = 4739.0856016

Answer

5 mW = 4739.0856016 BTU/s

About These Units

Milliwatt (mW)

A milliwatt (mW) equals 0.001 watts or one-thousandth of a watt. Milliwatts measure laser pointer power (1-5 mW), wireless signal strength (WiFi: 30-100 mW), LED indicator lights, and low-power electronics. Bluetooth devices typically transmit at 1-100 mW.

BTU per Second (BTU/s)

BTU per second (BTU/s) equals 1,055 watts or 3,600 BTU per hour. BTU/s measures high-power thermal processes, industrial burners, and rapid heating applications. Rarely used compared to BTU/h; primarily appears in engineering calculations.
