1, length unit conversion: 1 km = 1000 m (m), 1 m (m) = 100 cm (cm), 1 cm (cm) = 6544.
2. Area unit conversion: 1 km2 (km? ) = 1 ten thousand square meters (m? ), 1 m2 (m? ) = 100 square decimeter (dm? ), 1 square decimeter (dm? ) = 100 square centimeter (cm? )。
3. Volume conversion unit: 1 m3 (m? ) = 1000 cubic decimeter (dm? ), 1 cubic decimeter (dm? ) = 1000 cubic centimeter (cm? ), 1 cm3 (cm? ) = 1000 cubic millimeter (mm? )。
4. Conversion of mass unit: 1 ton (t)= 1000 kg = 1 kg (g),1g (g)= 1000 mg.
5. Conversion of temperature units: 1 Celsius (C) = 1 00 Fahrenheit (F),1Fahrenheit (F) = 32 Celsius (C).
6. Units of power conversion: 1 kW = 1000 watts (w), 1 watt (W)= 1000 joules (J)/ second).
7. Energy unit conversion: 1 joule (J)=0.239006 calories, 1 calorie = 4. 184 joules (j).
8. Force unit conversion: 1 Newton (N)= 1 kg m/s? (kg m/s? ), 1 kgf)=9.80665 Newton (n).
9. Speed unit conversion: 1m/s = 3.6km/h,1km/h =1000 m/3600s (m/s).
10, time unit conversion: 1 day (d)=24 hours (h), 1 hour (h)=60 minutes (min), 1 minute (min)=60 seconds (s).
Function of unit conversion formula:
1, the unit conversion formula is to facilitate people to convert between units. In daily life, we often need to use different units to represent the size or quantity of the same thing, such as length, area, volume and so on. By using the unit conversion formula, we can quickly convert one unit into another, thus better describing what we need to express.
The purpose of unit conversion formula is to improve our work efficiency and accuracy. In some scientific experiments or engineering calculations, a large number of unit conversions are often needed, and manual calculations will be very cumbersome and error-prone. Using the unit conversion formula, we can finish these tasks quickly and accurately, and improve the work efficiency and accuracy.
3. The purpose of the unit conversion formula is to expand our cognitive scope and cultural vision. Different countries and regions use different units and standards of measurement. If you don't master the relevant unit conversion formula, you may misunderstand the measurement methods and standards of the other party. By studying and applying the unit conversion formula, we can better understand and communicate cross-cultural things.
