Calculate Inductive reactance: H, 449kHz, 20.40575041173MΩ
This calculation can calculate the inductive reactance XL of an inductor knowing its inductance and the frequency. You can also calculate the inductance knowing the desired reactance and frequency, or calculate the frequency knowing the inductive reactance and inductance. XL = 2 π f L
Enter any 2 values, the 3rd one will be calculated:

Inductive reactance formula says:
•The inductive reactance (XL) of a 7.233131504513H (seven point two three three one three one five zero four five one three henrys) inductor at 449kHz (four hundred and fourty-nine kilohertz) is 20.40575041173MΩ (twenty point four zero five seven five zero four one one seven three megaohms).•For a 20.40575041173MΩ (twenty point four zero five seven five zero four one one seven three megaohms) inductive reactance at 449kHz (four hundred and fourty-nine kilohertz), you need a 7.233131504513H (seven point two three three one three one five zero four five one three henrys) inductor.
•A 7.233131504513H (seven point two three three one three one five zero four five one three henrys) inductor would have a 20.40575041173MΩ (twenty point four zero five seven five zero four one one seven three megaohms) reactance at 449kHz (four hundred and fourty-nine kilohertz) frequency.
