I know that many electronic scales these days can turn off automatically and do not consume batteries. The battery I use can last almost a year (I get up every morning to measure it...) I use Bailida's HD-366, you can find out. I heard that it seems to have a health scale that doesn't require batteries and uses solar power directly. . .
What is the pitch of a half thread RP?
Precise. In fact, the main function of the light energy scale is to weigh weight, but the scale has a solar panel that can convert light energy into electrical energy and store it in an internal rechargeable battery. It can be used continuously without changing the battery. Compared with ordinary battery storage scales, the solar scale does not need to replace the battery, so the solar scale is accurate.
rp1/2 is a type of t threadpipe sealed with threads. It is a cylindrical internal thread with a thread pitch of 21.224, a pitch diameter of 19.772, and a diameter of 18.321; p>Metric system It cannot be converted to inch system because ordinary threads are metric threads, which are mainly used on fasteners, while inch threads are mainly used on pipe threads and belong to two series , so they cannot be easily converted.
Detailed information
Main geometric parameters of cylindrical threads
1. The outer diameter (large diameter) coincides with the crest of the external thread or the bottom of the internal thread Diameter of the imaginary cylinder. The nominal diameter of the thread is the large diameter.
2. Inside diameter (small diameter), the diameter of the imaginary cylinder which coincides with the bottom of the external thread or the crest of the internal thread.
3. The pitch diameter, the diameter of the imaginary cylinder where the busbar passes through the tooth profile, and the width of the projection and groove are equal.
4. Pitch, the axial distance between adjacent teeth corresponding to two points on the median diameter line.
5. Lead, the axial distance between two corresponding points on the median diameter line of adjacent teeth on the same spiral.
6. Tooth profile angle, the angle between two adjacent flanks on the thread profile.
7. Wire rise angle, the angle between the tangent of the spiral on the average diameter cylinder and the plane perpendicular to the wire axis.
8. Working height, distance between the overlapping parts of the two corresponding thread profiles in the direction perpendicular to the thread axis, etc. Nominal thread diameter is the outside diameter, except pipe thread, which takes the inside diameter of the pipeau as nominal diameter. Threads are standardized and come in metric (metric) and imperial systems. The international standard adopts the metric system, and China also adopts the metric system.

How many millimeters is RP1-1/2?
1-1/2 is the inner hole of the pipe thread diameter, about 0.5-1 inch = 1.27 ~ 2.54 cm = 12.7 ~ 25.4 mm

How to convert imperial threads to metric threads, please give an example. THANKS!
1 inch = 25.4 mm if the thread has a nominal diameter of 1/4-20 D = 1/4 inch = 25.4 × (1/4) = 6.35 mm; pitch P = 20 teeth/inch = 25.4÷20 = 1.27 mm; Height of triangle H (tooth shape 55°) H = 0.866025404 (constant) × P = 0.866025404 × 1.27 = 1.099852263; pitch diameter = D-0.75 (constant) × H = 6.35-0.75 × 1.099852263 = 5.525110803; .5 × H=6.35-1.5×1.099852263=4.700221606. The above algorithm only applies to UK threads and is not suitable for calculating UK 'pipe' threads. (The pipe thread must therefore be looked up in a table, there is no algorithm.)
