98 kilometers per hour is approximately 60.8943 miles per hour (pmh).
The conversion from kilometers per hour (km/h) to miles per hour (pmh) involves multiplying the speed value by the factor 0.621371. This factor comes from the relation between a kilometer and a mile, where 1 km equals about 0.621371 miles. So, to convert 98 km/h into pmh, you multiply 98 by 0.621371.

Conversion Formula
The formula to convert kilometers per hour into miles per hour is:
pmh = km/h × 0.621371
This works because 1 kilometer equals approximately 0.621371 miles. Multiplying the speed in kilometers per hour by this factor converts the distance unit while keeping the time unit the same, resulting in miles per hour.
For example, converting 98 km/h:
- Start with 98 km/h.
- Multiply 98 by 0.621371.
- 98 × 0.621371 = 60.894358.
- So, 98 km/h is about 60.8943 miles per hour.
Conversion Example
- Convert 75 km/h to pmh:
- Multiply 75 by 0.621371.
- 75 × 0.621371 = 46.602825.
- Result: 75 km/h = 46.6028 pmh.
- Convert 110 km/h to pmh:
- 110 × 0.621371 = 68.35081.
- Result: 110 km/h = 68.3508 pmh.
- Convert 85.5 km/h to pmh:
- 85.5 × 0.621371 = 53.1171.
- Result: 85.5 km/h = 53.1171 pmh.
- Convert 100 km/h to pmh:
- 100 × 0.621371 = 62.1371.
- Result: 100 km/h = 62.1371 pmh.

Conversion Definitions
km (kilometer): A kilometer is a metric unit of length equal to 1,000 meters or about 0.621371 miles. It is used around the world for measuring distances, especially in countries that follow the metric system. Kilometers measure longer distances than meters and often used in road travel.
pmh (miles per hour): Miles per hour is a unit of speed expressing how many miles are traveled in one hour. Used primarily in the United States and United Kingdom, pmh measures speed for vehicles, runners, and others. One mile equals 1.60934 kilometers, so pmh is slower unit than km/h numerically.
Conversion FAQs
Why is the conversion factor from km to miles not a whole number?
The conversion factor 0.621371 comes from the precise length of a mile compared to a kilometer. Since the mile is defined as exactly 1,609.344 meters and the kilometer is 1,000 meters, their ratio is not a whole number. This precise value allows for accurate conversions.
Can I convert speeds without a calculator easily?
You can estimate by multiplying the kilometers per hour by 0.6, which gives a rough idea of miles per hour. But this method isn’t very accurate for precise needs. The exact factor 0.621371 is best for accurate conversions, especially for legal or scientific purposes.
Does converting km/h to pmh affect the time measurement?
No, the time unit ‘hour’ remains unchanged in the conversion. Only the distance unit changes from kilometers to miles. Therefore, the speed changes proportionally to the conversion factor but the time measurement stays the same.
Is there a reverse formula to convert pmh to km/h?
Yes, to convert miles per hour to kilometers per hour, multiply the pmh value by approximately 1.60934. This reverses the conversion and gives the speed in km/h.
Why do some speedometers show both km/h and pmh?
Vehicles designed for markets that use different measurement systems often have dual-speedometers. This allows drivers to understand their speed in both kilometers per hour and miles per hour, useful for traveling between countries using different systems.
