How to convert mph to kph

To convert an amount from miles per hour to kilometers per hour, you just need to multiply the amount by 1.609 (to 3dp)

How to convert kph to mph

To convert an amount from kilometers per hour to miles per hour, you just need to divide the amount by 1.609 (to 3dp).

1) Convert 75 miles per hour into kilometers per hour.

To convert 75 mph to kph we need to multiply the amount by 1.609 (to 3dp).

75 x 1.609 = 120.675 (to 3dp).

So 75 mph is 120.7 kph (to 1dp).

2) Convert 104 kilometers per hour into miles per hour.

To convert from kph into mph we need to divide by 1.609 (to 3dp)

104 ÷ 1.609 = 64.636

So 104 kph is 64.6 mph to 1dp.
