킬로미터/시을(를) 마일/시(으)로 변환하는 이유
킬로미터/시(km/h)과 마일/시(mph) 간의 변환은 가장 일반적인 속도 변환 중 하나입니다. 엔지니어링, 요리, 여행, 과학 등 어떤 분야에서든 km/h에서 mph으로의 빠른 변환은 시간을 절약하고 오류를 방지합니다.
Speed conversions from km/h to mph are critical for navigation, aviation, and sports analytics. Pilots and sailors must constantly convert between knots, km/h, and mph to ensure safe travel and comply with international air and maritime regulations. For motorists driving across borders, understanding local speed limits in a different unit is vital to avoid fines and accidents. In sports, analyzing the performance of sprinters, cyclists, or racing cars often involves comparing speeds recorded in different measurement systems. Accurate speed conversion ensures safety, legal compliance, and fair competitive analysis.
킬로미터/시을(를) 마일/시(으)로 변환하는 방법
킬로미터/시을(를) 마일/시(으)로 변환하려면 다음 공식을 사용하세요:
mph = km/h × 0.6213711922
예시: 1 km/h = 0.6213711922 mph
예를 들어, 5 km/h = 3.106855961 mph, 10 km/h = 6.213711922 mph, 100 km/h = 62.13711922 mph입니다. 더 큰 값: 1000 km/h = 621.3711922 mph. 역변환: 1 mph = 1.609344 km/h. 위의 계산기는 완전한 정밀도로 즉시 변환합니다 — 반올림 오류 없음.
일반적인 사용 사례
- Highway speed limit (China/EU): 120 km/h = 74.56454307 mph
- Urban speed limit (most countries): 50 km/h = 31.06855961 mph
- School zone speed limit: 30 km/h = 18.64113577 mph
- High-speed train (Shinkansen / CRH): 300 km/h = 186.4113577 mph
- National road speed limit (China): 80 km/h = 49.70969538 mph
피해야 할 일반적인 실수
- Knots vs MPH: a Knot is faster than a Mile per Hour (1 Knot = 1.15 mph).
- Mach numbers: speed of sound varies with temperature/altitude.
- Pace confusion: mixing up speed (distance/time) with pace (time/distance).
전문가 팁
- Highway math: 60 mph = 1 mile per minute. Easy for ETA calculation.
- KPH to MPH: Multiply km/h by 0.6 to get mph (approx).
- Light speed: Nothing travels faster than light (approx 300,000 km/s).
킬로미터/시(이)란?
Kilometers per hour (km/h) is a unit of speed, expressing the number of kilometers traveled in one hour.
Km/h is the standard unit for speed limits and vehicle speedometers in most countries worldwide (except the US and UK).
마일/시(이)란?
Miles per hour (mph) is a unit of speed in the Imperial and US customary systems, expressing miles traveled in one hour.
Mph is the standard unit for speed limits and vehicle speeds in the United States and the United Kingdom.
